Jann Horn discovered a race condition in the Unix domain socket
implementation in the Linux kernel that could result in a read-after-free.
A local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2021-4083)

Kirill Tkhai discovered that the XFS file system implementation in the
Linux kernel did not calculate size correctly when pre-allocating space in
some situations. A local attacker could use this to expose sensitive
information. (CVE-2021-4155)

Sushma Venkatesh Reddy discovered that the Intel i915 graphics driver in
the Linux kernel did not perform a GPU TLB flush in some situations. A
local attacker could use this to cause a denial of service or possibly
execute arbitrary code. (CVE-2022-0330)

It was discovered that the VMware Virtual GPU driver in the Linux kernel
did not properly handle certain failure conditions, leading to a stale
entry in the file descriptor table. A local attacker could use this to
expose sensitive information or possibly gain administrative privileges.
