Affected: AlmaLinux:8: bpftool, AlmaLinux:8: kernel, AlmaLinux:8: kernel-abi-stablelists, AlmaLinux:8: kernel-core, AlmaLinux:8: kernel-cross-headers, AlmaLinux:8: kernel-debug, AlmaLinux:8: kernel-debug-core, AlmaLinux:8: kernel-debug-devel, AlmaLinux:8: kernel-debug-modules, AlmaLinux:8: kernel-debug-modules-extra and 9 more

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666) * kernel: out-of-bounds read in fbcon_get_font function (CVE-2020-28915) 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): * weird port mapping with asymmetric traffic (BZ#2065266) * HBR3 is malfunction via MST HUB against Intel ADL-HX CPU (BZ#2066644) * openvswitch connection tracking sends incorrect flow key for some upcalls (BZ#2068476) * sctp connection abort unexpected. (BZ#2070959) * soft quota cannot exceed more the 5 warns which breaks timer functionality (BZ#2071713) * VirtIO Throughput for VM on host with OVS HW-Offload is very low (BZ#2074221) * SR-IOV performance > 50% degradation (BZ#2074829) * Call trace with parallel rules insertion and deletion (BZ#2075553) * Enable nested virtualization (BZ#2079069) * iscsi_ttx (iSERT) completions hung while waiting for mlx5_ib_drain_sq (BZ#2079433) * WARNING: CPU: 2 PID: 969 at kernel/locking/lockdep.c:895 register_lock_class+0x234/0x1640 (BZ#2079856) * mlx5: Some rule are not offloaded to HW in OVN K8s Pod 2 External use case (BZ#2079918) * OCP node kernel crash due to ceph_fsync - unsafe_request_wait+0x143 (BZ#2080071) * TCP doesn't retransmit if in reorder state and waits for RTO (BZ#2080972) *…
