Security Fix(es):

* kernel: use after free in eventpoll.c may lead to escalation of
privilege  (CVE-2020-0466)

* kernel: Use After Free in unix_gc() which could result in a local
privilege escalation (CVE-2021-0920)

* kernel: xfs: raw block device data leak in XFS_IOC_ALLOCSP IOCTL
(CVE-2021-4155)

* kernel: possible privileges escalation due to missing TLB flush
(CVE-2022-0330)

* kernel: failing usercopy allows for use-after-free exploitation
(CVE-2022-22942)

* kernel: out of bounds write in hid-multitouch.c may lead to escalation
of  privilege (CVE-2020-0465)

* kernel: double free in bluetooth subsystem when the HCI device
initialization fails (CVE-2021-3564)

* kernel: use-after-free in function hci_sock_bound_ioctl()
(CVE-2021-3573)

* kernel: possible use-after-free in bluetooth module (CVE-2021-3752)

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

Bug Fix(es):

* Kernel with enabled BERT does not decode CPU fatal events correctly

* SL 7.9 - Call trace seen during controller random reset on IB config

* Infinite loop in blk_set_queue_dying() from blk_queue_for_each_rl() when
another CPU races and modifies the queue's blkg_list

* NFS client kernel crash in NFS4 backchannel transmit path -
ftrace_raw_event_rpc_task_queued called from rpc_run_bc_task

* SELinux is preventing / from mount access on the filesystem /proc
