(RHSA-2022:5626) Important: kernel security and bug fix update

Description

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak (CVE-2022-1012) * kernel: race condition in perf_event_open leads to privilege escalation (CVE-2022-1729) * kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-32250) * kernel: cgroup: Use open-time creds and namespace for migration perm checks (CVE-2021-4197) * kernel: Race condition in races in sk_peer_pid and sk_peer_cred accesses (CVE-2021-4203) * kernel: the copy-on-write implementation can grant unintended write access because of a race condition in a THP mapcount check (CVE-2020-29368) 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): * Failed to reboot after crash trigger (BZ#2060747) * conntrack entries linger around after test (BZ#2066357) * Enable nested virtualization (BZ#2079070) * slub corruption during LPM of hnv interface (BZ#2081251) * sleeping function called from invalid context at kernel/locking/spinlock_rt.c:35 (BZ#2082091) * Backport request of "genirq: use rcu in kstat_irqs_usr()" (BZ#2083309) * ethtool -L may cause system to hang (BZ#2083323) * For isolated CPUs (with nohz_full enabled for isolated CPUs) CPU utilization statistics are not getting reflected continuously (BZ#2084139) * Affinity broken due to vector space exhaustion (BZ#2084647) * kernel memory leak while freeing nested actions (BZ#2086597) * sync rhel-8.6 with upstream 5.13 through 5.16 fixes and improvements (BZ#2088037) * Kernel panic possibly when cleaning namespace on pod deletion (BZ#2089539) * Softirq hrtimers are being placed on the per-CPU softirq clocks on isolcpu’s. (BZ#2090485) * fix missed wake-ups in rq_qos_throttle try two (BZ#2092076) * NFS4 client experiencing IO outages while sending duplicate SYNs and erroneous RSTs during connection reestablishment (BZ#2094334) * using __this_cpu_read() in preemptible [00000000] code: kworker/u66:1/937154 (BZ#2095775) * Need some changes in RHEL8.x kernels. (BZ#2096932)
