  script_tag(name:"insight", value:"This kernel-linus 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).

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).

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)

For other upstream fixes, see the referenced changelogs.");
