operating system.

Security Fix(es):

* kernel: stack overflow in do_proc_dointvec and proc_skip_spaces
(CVE-2022-4378)

* kernel: use-after-free related to leaf anon_vma double reuse
(CVE-2022-42703)

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):

* Regression - SAS3416 card works on RHEL 7.7 and below, does not work on
RHEL 7.8 or 7.9 (BZ#1974485)

* use-after-free in sctp_do_8_2_transport_strike (BZ#2054037)

* RHEL7.9 - [Regression] Kernel test failed during CPU polarization test -
lscpu, chcpu - LPAR (BZ#2071980)

* RHEL 7, block: Crash in blk_mq_rq_timed_out() when dereferencing NULL
request->q pointer (BZ#2088029)

* qla2xxx: Qlogic double completion races during error handling are still
not fixed and this will also  be a RHEL8+ exposure (BZ#2092105)

* kernel 3.10.0-1160.80.1.el7.x86_64 on Xeon E55xx crashes upon KVM startup
(BZ#2143438)

* Guest's time jumped forward by 12 minutes _after_ live-migration
completes (in 30 seconds) (BZ#2152838)

* RHEL7: target crashes if a malicious initiator sends a logout immediately
after a login command (BZ#2154243)

* RHEL7.9 - LTP testcase creat09 fails related to 'CVE-2018-13405' and
'CVE-2021-4037` (BZ#2159946)
