This kernel-linus update is based on upstream 5.15.15 and fixes atleast

A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS
filesystem allowed for size increase of files with unaligned size. A
local attacker could use this flaw to leak data on the XFS filesystem
otherwise not accessible to them (CVE-2021-4155).
An unprivileged write to the file handler flaw in the Linux kernel's
control groups and namespaces subsystem was found in the way users have
access to some less privileged process that are controlled by cgroups and
have higher privileged parent process. It is actually both for cgroup2
and cgroup1 versions of control groups. A local user could use this flaw
to crash the system or escalate their privileges on the system
(CVE-2021-4197).
A use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem in
