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)
