CVE-2022-23088 1 Freebsd 1 Freebsd 2025-06-04 9.8 Critical
The 802.11 beacon handling routine failed to validate the length of an IEEE 802.11s Mesh ID before copying it to a heap-allocated buffer. While a FreeBSD Wi-Fi client is in scanning mode (i.e., not associated with a SSID) a malicious beacon frame may overwrite kernel memory, leading to remote code execution.
CVE-2022-23093 1 Freebsd 1 Freebsd 2025-06-04 6.5 Medium
ping reads raw IP packets from the network to process responses in the pr_pack() function. As part of processing a response ping has to reconstruct the IP header, the ICMP header and if present a "quoted packet," which represents the packet that generated an ICMP error. The quoted packet again has an IP header and an ICMP header. The pr_pack() copies received IP and ICMP headers into stack buffers for further processing. In so doing, it fails to take into account the possible presence of IP option headers following the IP header in either the response or the quoted packet. When IP options are present, pr_pack() overflows the destination buffer by up to 40 bytes. The memory safety bugs described above can be triggered by a remote host, causing the ping program to crash. The ping process runs in a capability mode sandbox on all affected versions of FreeBSD and is thus very constrained in how it can interact with the rest of the system at the point where the bug can occur.
CVE-2022-23092 1 Freebsd 1 Freebsd 2025-06-04 8.8 High
The implementation of lib9p's handling of RWALK messages was missing a bounds check needed when unpacking the message contents. The missing check means that the receipt of a specially crafted message will cause lib9p to overwrite unrelated memory. The bug can be triggered by a malicious bhyve guest kernel to overwrite memory in the bhyve(8) process. This could potentially lead to user-mode code execution on the host, subject to bhyve's Capsicum sandbox.
CVE-2022-23091 1 Freebsd 1 Freebsd 2025-06-04 4 Medium
A particular case of memory sharing is mishandled in the virtual memory system. This is very similar to SA-21:08.vm, but with a different root cause. An unprivileged local user process can maintain a mapping of a page after it is freed, allowing that process to read private data belonging to other processes or the kernel.
CVE-2022-23090 1 Freebsd 1 Freebsd 2025-06-04 7.7 High
The aio_aqueue function, used by the lio_listio system call, fails to release a reference to a credential in an error case. An attacker may cause the reference count to overflow, leading to a use after free (UAF).
CVE-2024-25941 1 Freebsd 1 Freebsd 2025-06-04 3.3 Low
The jail(2) system call has not limited a visiblity of allocated TTYs (the kern.ttys sysctl). This gives rise to an information leak about processes outside the current jail. Attacker can get information about TTYs allocated on the host or in other jails. Effectively, the information printed by "pstat -t" may be leaked.
CVE-2024-25940 1 Freebsd 1 Freebsd 2025-06-04 6.3 Medium
`bhyveload -h <host-path>` may be used to grant loader access to the <host-path> directory tree on the host. Affected versions of bhyveload(8) do not make any attempt to restrict loader's access to <host-path>, allowing the loader to read any file the host user has access to. In the bhyveload(8) model, the host supplies a userboot.so to boot with, but the loader scripts generally come from the guest image. A maliciously crafted script could be used to exfiltrate sensitive data from the host accessible to the user running bhyhveload(8), which is often the system root.
CVE-2022-23089 1 Freebsd 1 Freebsd 2025-06-04 4.7 Medium
When dumping core and saving process information, proc_getargv() might return an sbuf which have a sbuf_len() of 0 or -1, which is not properly handled. An out-of-bound read can happen when user constructs a specially crafted ps_string, which in turn can cause the kernel to crash.
CVE-2022-27674 4 Amd, Freebsd, Linux and 1 more 4 Amd Uprof, Freebsd, Linux Kernel and 1 more 2025-05-01 7.5 High
Insufficient validation in the IOCTL input/output buffer in AMD μProf may allow an attacker to bypass bounds checks potentially leading to a Windows kernel crash resulting in denial of service.
CVE-2022-23831 4 Amd, Freebsd, Linux and 1 more 4 Amd Uprof, Freebsd, Linux Kernel and 1 more 2025-05-01 7.5 High
Insufficient validation of the IOCTL input buffer in AMD μProf may allow an attacker to send an arbitrary buffer leading to a potential Windows kernel crash resulting in denial of service.
CVE-2017-1087 1 Freebsd 1 Freebsd 2025-04-20 N/A
In FreeBSD 10.x before 10.4-STABLE, 10.4-RELEASE-p3, and 10.3-RELEASE-p24 named paths are globally scoped, meaning a process located in one jail can read and modify the content of POSIX shared memory objects created by a process in another jail or the host system. As a result, a malicious user that has access to a jailed system is able to abuse shared memory by injecting malicious content in the shared memory region. This memory region might be executed by applications trusting the shared memory, like Squid. This issue could lead to a Denial of Service or local privilege escalation.
CVE-2017-13081 7 Canonical, Debian, Freebsd and 4 more 12 Ubuntu Linux, Debian Linux, Freebsd and 9 more 2025-04-20 N/A
Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11w allows reinstallation of the Integrity Group Temporal Key (IGTK) during the group key handshake, allowing an attacker within radio range to spoof frames from access points to clients.
CVE-2017-13088 7 Canonical, Debian, Freebsd and 4 more 13 Ubuntu Linux, Debian Linux, Freebsd and 10 more 2025-04-20 N/A
Wi-Fi Protected Access (WPA and WPA2) that support 802.11v allows reinstallation of the Integrity Group Temporal Key (IGTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame, allowing an attacker within radio range to replay frames from access points to clients.
CVE-2015-5675 1 Freebsd 1 Freebsd 2025-04-20 N/A
The sys_amd64 IRET Handler in the kernel in FreeBSD 9.3 and 10.1 allows local users to gain privileges or cause a denial of service (kernel panic).
CVE-2017-1086 1 Freebsd 1 Freebsd 2025-04-20 N/A
In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p4, 11.0-RELEASE-p15, 10.4-STABLE, 10.4-RELEASE-p3, and 10.3-RELEASE-p24, not all information in the struct ptrace_lwpinfo is relevant for the state of any thread, and the kernel does not fill the irrelevant bytes or short strings. Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information of the kernel stack of the thread is possible from the debugger. As a result, some bytes from the kernel stack of the thread using ptrace (PT_LWPINFO) call can be observed in userspace.
CVE-2015-5677 1 Freebsd 1 Freebsd 2025-04-20 N/A
bsnmpd, as used in FreeBSD 9.3, 10.1, and 10.2, uses world-readable permissions on the snmpd.config file, which allows local users to obtain the secret key for USM authentication by reading the file.
CVE-2017-13079 7 Canonical, Debian, Freebsd and 4 more 12 Ubuntu Linux, Debian Linux, Freebsd and 9 more 2025-04-20 N/A
Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11w allows reinstallation of the Integrity Group Temporal Key (IGTK) during the four-way handshake, allowing an attacker within radio range to spoof frames from access points to clients.
CVE-2017-1088 1 Freebsd 1 Freebsd 2025-04-20 N/A
In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p4, 11.0-RELEASE-p15, 10.4-STABLE, 10.4-RELEASE-p3, and 10.3-RELEASE-p24, the kernel does not properly clear the memory of the kld_file_stat structure before filling the data. Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information from the kernel stack is possible. As a result, some bytes from the kernel stack can be observed in userspace.
CVE-2017-6257 5 Freebsd, Linux, Microsoft and 2 more 5 Freebsd, Kernel, Windows and 2 more 2025-04-20 N/A
NVIDIA GPU Display Driver contains a vulnerability in the kernel mode layer handler where a NULL pointer dereference may lead to denial of service or potential escalation of privileges
CVE-2017-13080 7 Canonical, Debian, Freebsd and 4 more 13 Ubuntu Linux, Debian Linux, Freebsd and 10 more 2025-04-20 N/A
Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients.
