Important: kernel security, bug fix, and enhancement update

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: stack overflow in do_proc_dointvec and proc_skip_spaces (CVE-2022-4378) * ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF (CVE-2023-0266) * kernel: FUSE filesystem low-privileged user privileges escalation (CVE-2023-0386) * kernel: net: CPU soft lockup in TC mirred egress-to-ingress action (CVE-2022-4269) 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): * kernel panic on reboot due to a bug in mei_wdt module (BZ#2139770) * AlmaLinux8: Practically limit "Dummy wait" workaround to old Intel systems (BZ#2142170) * AMDSERVER 8.7: amdpstate driver incorrectly designed to load as default for Genoa (BZ#2151275) * AlmaLinux-8.8: Update RDMA core to Linux v6.0 (BZ#2161750) * Kernel panic observed during VxFS module unload (BZ#2162763) * Client not able to connect to almalinux server: SYN is answered by chalange ACK and RST is ignored (BZ#2165587) * AlmaLinux8.4: s390/kexec: fix ipl report address for kdump (BZ#2166296) * kvm-unit-test reports unhandled exception on AMD (BZ#2166362) * Windows Server 2019 guest randomly pauses with "KVM: entry failed, hardware error 0x80000021" (BZ#2166368) * Unable to get QinQ working with ConnectX-4 Lx in SR-IOV scenario (BZ#2166665) * panic in fib6_rule_suppress+0x22 with custom xdp prog involved in (BZ#2167602) * net/mlx5e: Fix use-after-free when reverting termination table (BZ#2167640) * AlmaLinux 8.7: EEH injection failed to recover on Mellanox adapter.
