CVE-2023-52730 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-09-23 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: mmc: sdio: fix possible resource leaks in some error paths If sdio_add_func() or sdio_init_func() fails, sdio_remove_func() can not release the resources, because the sdio function is not presented in these two cases, it won't call of_node_put() or put_device(). To fix these leaks, make sdio_func_present() only control whether device_del() needs to be called or not, then always call of_node_put() and put_device(). In error case in sdio_init_func(), the reference of 'card->dev' is not get, to avoid redundant put in sdio_free_func_cis(), move the get_device() to sdio_alloc_func() and put_device() to sdio_release_func(), it can keep the get/put function be balanced. Without this patch, while doing fault inject test, it can get the following leak reports, after this fix, the leak is gone. unreferenced object 0xffff888112514000 (size 2048): comm "kworker/3:2", pid 65, jiffies 4294741614 (age 124.774s) hex dump (first 32 bytes): 00 e0 6f 12 81 88 ff ff 60 58 8d 06 81 88 ff ff ..o.....`X...... 10 40 51 12 81 88 ff ff 10 40 51 12 81 88 ff ff .@Q......@Q..... backtrace: [<000000009e5931da>] kmalloc_trace+0x21/0x110 [<000000002f839ccb>] mmc_alloc_card+0x38/0xb0 [mmc_core] [<0000000004adcbf6>] mmc_sdio_init_card+0xde/0x170 [mmc_core] [<000000007538fea0>] mmc_attach_sdio+0xcb/0x1b0 [mmc_core] [<00000000d4fdeba7>] mmc_rescan+0x54a/0x640 [mmc_core] unreferenced object 0xffff888112511000 (size 2048): comm "kworker/3:2", pid 65, jiffies 4294741623 (age 124.766s) hex dump (first 32 bytes): 00 40 51 12 81 88 ff ff e0 58 8d 06 81 88 ff ff .@Q......X...... 10 10 51 12 81 88 ff ff 10 10 51 12 81 88 ff ff ..Q.......Q..... backtrace: [<000000009e5931da>] kmalloc_trace+0x21/0x110 [<00000000fcbe706c>] sdio_alloc_func+0x35/0x100 [mmc_core] [<00000000c68f4b50>] mmc_attach_sdio.cold.18+0xb1/0x395 [mmc_core] [<00000000d4fdeba7>] mmc_rescan+0x54a/0x640 [mmc_core]

In the Linux kernel, the following vulnerability has been resolved: net/usb: kalmia: Don't pass act_len in usb_bulk_msg error path syzbot reported that act_len in kalmia_send_init_packet() is uninitialized when passing it to the first usb_bulk_msg error path. Jiri Pirko noted that it's pointless to pass it in the error path, and that the value that would be printed in the second error path would be the value of act_len from the first call to usb_bulk_msg.[1] With this in mind, let's just not pass act_len to the usb_bulk_msg error paths. 1: https://lore.kernel.org/lkml/Y9pY61y1nwTuzMOa@nanopsycho/
CVE-2021-47647 1 Linux 1 Linux Kernel 2025-09-23 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: clk: qcom: ipq8074: fix PCI-E clock oops Fix PCI-E clock related kernel oops that are caused by a missing clock parent. pcie0_rchng_clk_src has num_parents set to 2 but only one parent is actually set via parent_hws, it should also have "XO" defined. This will cause the kernel to panic on a NULL pointer in clk_core_get_parent_by_index(). So, to fix this utilize clk_parent_data to provide gcc_xo_gpll0 parent data. Since there is already an existing static const char * const gcc_xo_gpll0[] used to provide the same parents via parent_names convert those users to clk_parent_data as well. Without this earlycon is needed to even catch the OOPS as it will reset the board before serial is initialized with the following: [ 0.232279] Unable to handle kernel paging request at virtual address 0000a00000000000 [ 0.232322] Mem abort info: [ 0.239094] ESR = 0x96000004 [ 0.241778] EC = 0x25: DABT (current EL), IL = 32 bits [ 0.244908] SET = 0, FnV = 0 [ 0.250377] EA = 0, S1PTW = 0 [ 0.253236] FSC = 0x04: level 0 translation fault [ 0.256277] Data abort info: [ 0.261141] ISV = 0, ISS = 0x00000004 [ 0.264262] CM = 0, WnR = 0 [ 0.267820] [0000a00000000000] address between user and kernel address ranges [ 0.270954] Internal error: Oops: 96000004 [#1] SMP [ 0.278067] Modules linked in: [ 0.282751] CPU: 1 PID: 1 Comm: swapper/0 Not tainted 5.15.10 #0 [ 0.285882] Hardware name: Xiaomi AX3600 (DT) [ 0.292043] pstate: 20400005 (nzCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 0.296299] pc : clk_core_get_parent_by_index+0x68/0xec [ 0.303067] lr : __clk_register+0x1d8/0x820 [ 0.308273] sp : ffffffc01111b7d0 [ 0.312438] x29: ffffffc01111b7d0 x28: 0000000000000000 x27: 0000000000000040 [ 0.315919] x26: 0000000000000002 x25: 0000000000000000 x24: ffffff8000308800 [ 0.323037] x23: ffffff8000308850 x22: ffffff8000308880 x21: ffffff8000308828 [ 0.330155] x20: 0000000000000028 x19: ffffff8000309700 x18: 0000000000000020 [ 0.337272] x17: 000000005cc86990 x16: 0000000000000004 x15: ffffff80001d9d0a [ 0.344391] x14: 0000000000000000 x13: 0000000000000000 x12: 0000000000000006 [ 0.351508] x11: 0000000000000003 x10: 0101010101010101 x9 : 0000000000000000 [ 0.358626] x8 : 7f7f7f7f7f7f7f7f x7 : 6468626f5e626266 x6 : 17000a3a403c1b06 [ 0.365744] x5 : 061b3c403a0a0017 x4 : 0000000000000000 x3 : 0000000000000001 [ 0.372863] x2 : 0000a00000000000 x1 : 0000000000000001 x0 : ffffff8000309700 [ 0.379982] Call trace: [ 0.387091] clk_core_get_parent_by_index+0x68/0xec [ 0.389351] __clk_register+0x1d8/0x820 [ 0.394210] devm_clk_hw_register+0x5c/0xe0 [ 0.398030] devm_clk_register_regmap+0x44/0x8c [ 0.402198] qcom_cc_really_probe+0x17c/0x1d0 [ 0.406711] qcom_cc_probe+0x34/0x44 [ 0.411224] gcc_ipq8074_probe+0x18/0x30 [ 0.414869] platform_probe+0x68/0xe0 [ 0.418776] really_probe.part.0+0x9c/0x30c [ 0.422336] __driver_probe_device+0x98/0x144 [ 0.426329] driver_probe_device+0x44/0x11c [ 0.430842] __device_attach_driver+0xb4/0x120 [ 0.434836] bus_for_each_drv+0x68/0xb0 [ 0.439349] __device_attach+0xb0/0x170 [ 0.443081] device_initial_probe+0x14/0x20 [ 0.446901] bus_probe_device+0x9c/0xa4 [ 0.451067] device_add+0x35c/0x834 [ 0.454886] of_device_add+0x54/0x64 [ 0.458360] of_platform_device_create_pdata+0xc0/0x100 [ 0.462181] of_platform_bus_create+0x114/0x370 [ 0.467128] of_platform_bus_create+0x15c/0x370 [ 0.471641] of_platform_populate+0x50/0xcc [ 0.476155] of_platform_default_populate_init+0xa8/0xc8 [ 0.480324] do_one_initcall+0x50/0x1b0 [ 0.485877] kernel_init_freeable+0x234/0x29c [ 0.489436] kernel_init+0x24/0x120 [ 0.493948] ret_from_fork+0x10/0x20 [ 0.497253] Code: d50323bf d65f03c0 f94002a2 b4000302 (f9400042) [ 0.501079] ---[ end trace 4ca7e1129da2abce ]---

In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: fix a potential gpu_metrics_table memory leak Memory is allocated for gpu_metrics_table in renoir_init_smc_tables(), but not freed in int smu_v12_0_fini_smc_tables(). Free it!
CVE-2021-47650 1 Linux 1 Linux Kernel 2025-09-23 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: ASoC: soc-compress: prevent the potentially use of null pointer There is one call trace that snd_soc_register_card() ->snd_soc_bind_card()->soc_init_pcm_runtime() ->snd_soc_dai_compress_new()->snd_soc_new_compress(). In the trace the 'codec_dai' transfers from card->dai_link, and we can see from the snd_soc_add_pcm_runtime() in snd_soc_bind_card() that, if value of card->dai_link->num_codecs is 0, then 'codec_dai' could be null pointer caused by index out of bound in 'asoc_rtd_to_codec(rtd, 0)'. And snd_soc_register_card() is called by various platforms. Therefore, it is better to add the check in the case of misusing. And because 'cpu_dai' has already checked in soc_init_pcm_runtime(), there is no need to check again. Adding the check as follow, then if 'codec_dai' is null, snd_soc_new_compress() will not pass through the check 'if (playback + capture != 1)', avoiding the leftover use of 'codec_dai'.

In the Linux kernel, the following vulnerability has been resolved: ubifs: Fix to add refcount once page is set private MM defined the rule [1] very clearly that once page was set with PG_private flag, we should increment the refcount in that page, also main flows like pageout(), migrate_page() will assume there is one additional page reference count if page_has_private() returns true.

There are 2 situations: Situation 1: refcount is 3, page is created by __page_cache_alloc. TYPE_A - the write process is using this page TYPE_B - page is assigned to one certain mapping by calling __add_to_page_cache_locked() TYPE_C - page is added into pagevec list corresponding current cpu by calling lru_cache_add() Situation 2: refcount is 2, page is gotten from the mapping's tree TYPE_B - page has been assigned to one certain mapping TYPE_A - the write process is using this page (by calling page_cache_get_speculative()) Filesystem releases one refcount by calling put_page() in xxx_write_end(), the released refcount corresponds to TYPE_A (write task is using it). If there are any processes using a page, page migration process will skip the page by judging whether expected_page_refs() equals to page refcount. The BUG is caused by following process: PA(cpu 0) kcompactd(cpu 1) compact_zone ubifs_write_begin page_a = grab_cache_page_write_begin add_to_page_cache_lru lru_cache_add pagevec_add // put page into cpu 0's pagevec (refcnf = 3, for page creation process) ubifs_write_end SetPagePrivate(page_a) // doesn't increase page count ! unlock_page(page_a) put_page(page_a) // refcnt = 2 [...] PB(cpu 0) filemap_read filemap_get_pages add_to_page_cache_lru lru_cache_add __pagevec_lru_add // traverse all pages in cpu 0's pagevec __pagevec_lru_add_fn SetPageLRU(page_a) isolate_migratepages isolate_migratepages_block get_page_unless_zero(page_a) // refcnt = 3 list_add(page_a, from_list) migrate_pages(from_list) __unmap_and_move move_to_new_page ubifs_migrate_page(page_a) migrate_page_move_mapping expected_page_refs get 3 (migration[1] + mapping[1] + private[1]) release_pages put_page_testzero(page_a) // refcnt = 3 page_ref_freeze // refcnt = 0 page_ref_dec_and_test(0 - 1 = -1) page_ref_unfreeze VM_BUG_ON_PAGE(-1 != 0, page) UBIFS doesn't increase the page refcount after setting private flag, which leads to page migration task believes the page is not used by any other processes, so the page is migrated. This causes concurrent accessing on page refcount between put_page() called by other process(eg. read process calls lru_cache_add) and page_ref_unfreeze() called by mi ---truncated---
CVE-2024-36001 1 Linux 1 Linux Kernel 2025-09-23 7.8 High
In the Linux kernel, the following vulnerability has been resolved: netfs: Fix the pre-flush when appending to a file in writethrough mode In netfs_perform_write(), when the file is marked NETFS_ICTX_WRITETHROUGH or O_*SYNC or RWF_*SYNC was specified, write-through caching is performed on a buffered file. When setting up for write-through, we flush any conflicting writes in the region and wait for the write to complete, failing if there's a write error to return. The issue arises if we're writing at or above the EOF position because we skip the flush and - more importantly - the wait. This becomes a problem if there's a partial folio at the end of the file that is being written out and we want to make a write to it too. Both the already-running write and the write we start both want to clear the writeback mark, but whoever is second causes a warning looking something like: ------------[ cut here ]------------ R=00000012: folio 11 is not under writeback WARNING: CPU: 34 PID: 654 at fs/netfs/write_collect.c:105 ...

RIP: 0010:netfs_writeback_lookup_folio Fix this by making the flush-and-wait unconditional. It will do nothing if there are no folios in the pagecache and will return quickly if there are no folios in the region specified. Further, move the WBC attachment above the flush call as the flush is going to attach a WBC and detach it again if it is not present - and since we need one anyway we might as well share it.
CVE-2022-49084 1 Linux 1 Linux Kernel 2025-09-23 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: qede: confirm skb is allocated before using qede_build_skb() assumes build_skb() always works and goes straight to skb_reserve(). However, build_skb() can fail under memory pressure. This results in a kernel panic because the skb to reserve is NULL. Add a check in case build_skb() failed to allocate and return NULL. The NULL return is handled correctly in callers to qede_build_skb().

Looks like the regression already happened with an earlier commit 6785eb9105e3 ("iommu/omap: Convert to probe/release_device() call-backs") that changed the function return type and missed converting one place.

In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: fix mpol_new leak in shared_policy_replace If mpol_new is allocated but not used in restart loop, mpol_new will be freed via mpol_put before returning to the caller. But refcnt is not initialized yet, so mpol_put could not do the right things and might leak the unused mpol_new. This would happen if mempolicy was updated on the shared shmem file while the sp->lock has been dropped during the memory allocation. This issue could be triggered easily with the below code snippet if there are many processes doing the below work at the same time: shmid = shmget((key_t)5566, 1024 * PAGE_SIZE, 0666|IPC_CREAT); shm = shmat(shmid, 0, 0); loop many times { mbind(shm, 1024 * PAGE_SIZE, MPOL_LOCAL, mask, maxnode, 0); mbind(shm + 128 * PAGE_SIZE, 128 * PAGE_SIZE, MPOL_DEFAULT, mask, maxnode, 0); }

In the Linux kernel, the following vulnerability has been resolved: ata: sata_dwc_460ex: Fix crash due to OOB write the driver uses libata's "tag" values from in various arrays. Since the mentioned patch bumped the ATA_TAG_INTERNAL to 32, the value of the SATA_DWC_QCMD_MAX needs to account for that. Otherwise ATA_TAG_INTERNAL usage cause similar crashes like this as reported by Tice Rex on the OpenWrt Forum and reproduced (with symbols) here: | BUG: Kernel NULL pointer dereference at 0x00000000 | Faulting instruction address: 0xc03ed4b8 | Oops: Kernel access of bad area, sig: 11 [#1] | BE PAGE_SIZE=4K PowerPC 44x Platform | CPU: 0 PID: 362 Comm: scsi_eh_1 Not tainted 5.4.163 #0 | NIP: c03ed4b8 LR: c03d27e8 CTR: c03ed36c | REGS: cfa59950 TRAP: 0300 Not tainted (5.4.163) | MSR: 00021000 <CE,ME> CR: 42000222 XER: 00000000 | DEAR: 00000000 ESR: 00000000 | GPR00: c03d27e8 cfa59a08 cfa55fe0 00000000 0fa46bc0 [...] | [..] | NIP [c03ed4b8] sata_dwc_qc_issue+0x14c/0x254 | LR [c03d27e8] ata_qc_issue+0x1c8/0x2dc | Call Trace: | [cfa59a08] [c003f4e0] __cancel_work_timer+0x124/0x194 (unreliable) | [cfa59a78] [c03d27e8] ata_qc_issue+0x1c8/0x2dc | [cfa59a98] [c03d2b3c] ata_exec_internal_sg+0x240/0x524 | [cfa59b08] [c03d2e98] ata_exec_internal+0x78/0xe0 | [cfa59b58] [c03d30fc] ata_read_log_page.part.38+0x1dc/0x204 | [cfa59bc8] [c03d324c] ata_identify_page_supported+0x68/0x130 | [...] This is because sata_dwc_dma_xfer_complete() NULLs the dma_pending's next neighbour "chan" (a *dma_chan struct) in this '32' case right here (line ~735): > hsdevp->dma_pending[tag] = SATA_DWC_DMA_PENDING_NONE; Then the next time, a dma gets issued; dma_dwc_xfer_setup() passes the NULL'd hsdevp->chan to the dmaengine_slave_config() which then causes the crash. With this patch, SATA_DWC_QCMD_MAX is now set to ATA_MAX_QUEUE + 1. This avoids the OOB. But please note, there was a worthwhile discussion on what ATA_TAG_INTERNAL and ATA_MAX_QUEUE is. And why there should not be a "fake" 33 command-long queue size. Ideally, the dw driver should account for the ATA_TAG_INTERNAL. In Damien Le Moal's words: "... having looked at the driver, it is a bigger change than just faking a 33rd "tag" that is in fact not a command tag at all."

In the Linux kernel, the following vulnerability has been resolved: block: null_blk: end timed out poll request When poll request is timed out, it is removed from the poll list, but not completed, so the request is leaked, and never get chance to complete. Fix the issue by ending it in timeout handler.

In the Linux kernel, the following vulnerability has been resolved: net: usb: aqc111: Fix out-of-bounds accesses in RX fixup aqc111_rx_fixup() contains several out-of-bounds accesses that can be triggered by a malicious (or defective) USB device, in particular: - The metadata array (desc_offset..desc_offset+2*pkt_count) can be out of bounds, causing OOB reads and (on big-endian systems) OOB endianness flips. - A packet can overlap the metadata array, causing a later OOB endianness flip to corrupt data used by a cloned SKB that has already been handed off into the network stack. - A packet SKB can be constructed whose tail is far beyond its end, causing out-of-bounds heap data to be considered part of the SKB's data. Found doing variant analysis. Tested it with another driver (ax88179_178a), since I don't have a aqc111 device to test it, but the code looks very similar.

CVE-2022-49044 1 Linux 1 Linux Kernel 2025-09-23 7.8 High
In the Linux kernel, the following vulnerability has been resolved: dm integrity: fix memory corruption when tag_size is less than digest size It is possible to set up dm-integrity in such a way that the "tag_size" parameter is less than the actual digest size. In this situation, a part of the digest beyond tag_size is ignored. In this case, dm-integrity would write beyond the end of the ic->recalc_tags array and corrupt memory. The corruption happened in integrity_recalc->integrity_sector_checksum->crypto_shash_final. Fix this corruption by increasing the tags array so that it has enough padding at the end to accomodate the loop in integrity_recalc() being able to write a full digest size for the last member of the tags array.

In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: fix missing hugetlb_lock for resv uncharge There is a recent report on UFFDIO_COPY over hugetlb: https://lore.kernel.org/all/000000000000ee06de0616177560@google.com/ 350: lockdep_assert_held(&hugetlb_lock); Should be an issue in hugetlb but triggered in an userfault context, where it goes into the unlikely path where two threads modifying the resv map together. Mike has a fix in that path for resv uncharge but it looks like the locking criteria was overlooked: hugetlb_cgroup_uncharge_folio_rsvd() will update the cgroup pointer, so it requires to be called with the lock held.

In the Linux kernel, the following vulnerability has been resolved: ceph: fix inode reference leakage in ceph_get_snapdir() The ceph_get_inode() will search for or insert a new inode into the hash for the given vino, and return a reference to it. If new is non-NULL, its reference is consumed. We should release the reference when in error handing cases.
