| CVE-2023-4622 | 3 Debian, Linux, Redhat | 9 Debian Linux, Linux Kernel, Enterprise Linux and 6 more | 2025-02-13 | 7.8 High |
| A use-after-free vulnerability in the Linux kernel's af_unix component can be exploited to achieve local privilege escalation. The unix_stream_sendpage() function tries to add data to the last skb in the peer's recv queue without locking the queue. Thus there is a race where unix_stream_sendpage() could access an skb locklessly that is being released by garbage collection, resulting in use-after-free. We recommend upgrading past commit 790c2f9d15b594350ae9bca7b236f2b1859de02c. | ||||
| CVE-2023-3611 | 3 Debian, Linux, Redhat | 11 Debian Linux, Kernel, Linux Kernel and 8 more | 2025-02-13 | 7.8 High |
| An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64. | ||||
| CVE-2023-20593 | 4 Amd, Debian, Redhat and 1 more | 147 Athlon Gold 7220u, Athlon Gold 7220u Firmware, Epyc 7232p and 144 more | 2025-02-13 | 5.5 Medium |
| An issue in “Zen 2” CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information. | ||||
| CVE-2023-1998 | 3 Debian, Linux, Redhat | 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more | 2025-02-13 | 5.6 Medium |
| The Linux kernel allows userspace processes to enable mitigations by calling prctl with PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened because when plain IBRS was enabled (not enhanced IBRS), the kernel had some logic that determined that STIBP was not needed. The IBRS bit implicitly protects against cross-thread branch target injection. However, with legacy IBRS, the IBRS bit was cleared on returning to userspace, due to performance reasons, which disabled the implicit STIBP and left userspace threads vulnerable to cross-thread branch target injection against which STIBP protects. | ||||
| CVE-2023-1829 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2025-02-13 | 7.8 High |
| A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate filters in case of a perfect hashes while deleting the underlying structure which can later lead to double freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root. We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28. | ||||
| CVE-2022-2196 | 3 Debian, Linux, Redhat | 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more | 2025-02-13 | 5.8 Medium |
| A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past commit 2e7eab81425a | ||||
| CVE-2023-35001 | 5 Debian, Fedoraproject, Linux and 2 more | 15 Debian Linux, Fedora, Linux Kernel and 12 more | 2025-02-13 | 7.8 High |
| Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace | ||||
| CVE-2023-3390 | 3 Linux, Netapp, Redhat | 12 Linux Kernel, H300s, H410c and 9 more | 2025-02-13 | 7.8 High |
| A use-after-free vulnerability was found in the Linux kernel's netfilter subsystem in net/netfilter/nf_tables_api.c. Mishandled error handling with NFT_MSG_NEWRULE makes it possible to use a dangling pointer in the same transaction causing a use-after-free vulnerability. This flaw allows a local attacker with user access to cause a privilege escalation issue. We recommend upgrading past commit 1240eb93f0616b21c675416516ff3d74798fdc97. | ||||
| CVE-2023-0461 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Rhel Aus and 4 more | 2025-02-13 | 7.8 High |
| There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this socket is disconnected and reused as a listener. If a new socket is created from the listener, the context is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c | ||||
| CVE-2023-0458 | 3 Debian, Linux, Redhat | 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more | 2025-02-13 | 5.3 Medium |
| A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be used to leak the contents. We recommend upgrading past version 6.1.8 or commit 739790605705ddcf18f21782b9c99ad7d53a8c11 | ||||
| CVE-2022-40982 | 5 Debian, Intel, Netapp and 2 more | 1058 Debian Linux, Celeron 5205u, Celeron 5205u Firmware and 1055 more | 2025-02-13 | 6.5 Medium |
| Information exposure through microarchitectural state after transient execution in certain vector execution units for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. | ||||
| CVE-2022-28733 | 2 Gnu, Redhat | 5 Grub2, Enterprise Linux, Rhel E4s and 2 more | 2025-02-13 | 8.1 High |
| Integer underflow in grub_net_recv_ip4_packets; A malicious crafted IP packet can lead to an integer underflow in grub_net_recv_ip4_packets() function on rsm->total_len value. Under certain circumstances the total_len value may end up wrapping around to a small integer number which will be used in memory allocation. If the attack succeeds in such way, subsequent operations can write past the end of the buffer. | ||||
| CVE-2022-23521 | 2 Git-scm, Redhat | 8 Git, Enterprise Linux, Rhel Aus and 5 more | 2025-02-13 | 9.8 Critical |
| Git is distributed revision control system. gitattributes are a mechanism to allow defining attributes for paths. These attributes can be defined by adding a `.gitattributes` file to the repository, which contains a set of file patterns and the attributes that should be set for paths matching this pattern. When parsing gitattributes, multiple integer overflows can occur when there is a huge number of path patterns, a huge number of attributes for a single pattern, or when the declared attribute names are huge. These overflows can be triggered via a crafted `.gitattributes` file that may be part of the commit history. Git silently splits lines longer than 2KB when parsing gitattributes from a file, but not when parsing them from the index. Consequentially, the failure mode depends on whether the file exists in the working tree, the index or both. This integer overflow can result in arbitrary heap reads and writes, which may result in remote code execution. The problem has been patched in the versions published on 2023-01-17, going back to v2.30.7. Users are advised to upgrade. There are no known workarounds for this issue. | ||||

| Incorrect default permissions in some memory controller configurations for some Intel(R) Xeon(R) Processors when using Intel(R) Software Guard Extensions which may allow a privileged user to potentially enable escalation of privilege via local access. | ||||
| CVE-2023-3006 | 2 Linux, Redhat | 3 Linux Kernel, Rhel Eus, Rhev Hypervisor | 2025-01-09 | 5.5 Medium |
| A known cache speculation vulnerability, known as Branch History Injection (BHI) or Spectre-BHB, becomes actual again for the new hw AmpereOne. Spectre-BHB is similar to Spectre v2, except that malicious code uses the shared branch history (stored in the CPU Branch History Buffer, or BHB) to influence mispredicted branches within the victim's hardware context. Once that occurs, speculation caused by the mispredicted branches can cause cache allocation. This issue leads to obtaining information that should not be accessible. | ||||
