3. Description:

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es):

* Incomplete cleanup of multi-core shared buffers (aka SBDR)
(CVE-2022-21123)

* Incomplete cleanup of microarchitectural fill buffers (aka SBDS)
(CVE-2022-21125)

* Incomplete cleanup in specific special register write operations (aka
DRPW) (CVE-2022-21166)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.

Bug Fix(es):

* SolarFlare sfc spurious TX completion (BZ#1793280)

* Page allocation failure on cryptsetup open (BZ#2072970)

* The kernel-rt crashes where one task is indefinitely looping in
__start_cfs_bandwidth() with the cfs_b->lock spinlock being held
(BZ#2077346)

* While using PTimekeeper the qede driver produces excessive log messages
(BZ#2080646)

* The kernel crashes due to a GPF happens in mutex_spin_on_owner(). The
known RDMA/cma bug that was introduced with a patch from upstream commit
722c7b2bfead is the possible cause. (BZ#2085425)

* Running LTP testcase creat09 fails showing related  to 'cve-2018-13405'
(BZ#2089360)

* Crash when releasing inode which was on unmouted superblock (BZ#2096884)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:
