CVE-2022-0435

The Linux Kernel, the operating system core itself. Security Fix(es): In memory management driver, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.(CVE-2022-0492) An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor.(CVE-2022-24448) A stack overflow flaw was found in the Linux kernel’s TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed. This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network.(CVE-2022-0435) An issue was discovered in the Linux kernel before 5.16.5. There is a memory leak in yam_siocdevprivate in drivers/net/hamradio/yam.c.(CVE-2022-24959) drivers/usb/gadget/legacy/inode.c in the Linux kernel through 5.16.8 mishandles dev->buf release.(CVE-2022-24958)

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

• kernel: improper initialization of the "flags" member of the new pipe_buffer (CVE-2022-0847)

• kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920)

This kernel update is based on upstream 5.15.23 and fixes at least the following security issues:

A stack overflow flaw was found in the Linux kernel TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed. This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network (CVE-2022-0435).

A vulnerability was found in the Linux kernel cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly (CVE-2022-0492).

An issue was discovered in fs/nfs/dir.c in the Linux kernel before 5.16.5. If an application sets the O_DIRECTORY flag, and tries to open a regular file, nfs_atomic_open() performs a regular lookup. If a regular file is found, ENOTDIR should occur, but the server instead returns uninitialized data in the file descriptor (CVE-2022-24448).

Other fixes in this update:

• enable several missed MediaTek wifi drivers (mga#29965)

kernel/ucount.c in the Linux kernel 5.14 through 5.16.4, when unprivileged user namespaces are enabled, allows a use-after-free and privilege escalation because a ucounts object can outlive its namespace (CVE-2022-24122).

Yiqi Sun and Kevin Wang discovered that the cgroups implementation in the Linux kernel did not properly restrict access to the cgroups v1 release_agent feature. A local attacker could use this to gain administrative privileges. (CVE-2022-0492)

Brendan Dolan-Gavitt discovered that the Marvell WiFi-Ex USB device driver in the Linux kernel did not properly handle some error conditions. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2021-43976)

Wenqing Liu discovered that the f2fs file system implementation in the Linux kernel did not properly validate inode types while performing garbage collection. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service (system crash). (CVE-2021-44879)

Samuel Page discovered that the Transparent Inter-Process Communication (TIPC) protocol implementation in the Linux kernel contained a stack-based buffer overflow. A remote attacker could use this to cause a denial of service (system crash) for systems that have a TIPC bearer configured. (CVE-2022-0435)

Lyu Tao discovered that the NFS implementation in the Linux kernel did not properly handle requests to open a directory on a regular file. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-24448)

It was discovered that the YAM AX.25 device driver in the Linux kernel did not properly deallocate memory in some error conditions. A local privileged attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2022-24959)
