The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: * kernel: use-after-free in drivers/infiniband/core/ucma.c ctx use-after-free * kernel: out-of-bounds write due to a heap buffer overflow in __hidinput_change_resolution_multipliers of hid-input.c * kernel: SVM nested virtualization issue in KVM For more details about the security issue, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section. Bug Fix: * [HPE 8.3 bug] No EDAC MC0 message with one-DIMM two-processor configuration under RHEL8.3 * mlx: devlink port function shows all zero hw_addr * net/sched: act_mirred: allow saving the last chain processed on xmit path * RHEL8.3 - System hang and / or r/o fs during SVC/v5k/v7k maintenance with ibmvfc * RHEL8.1 Snapshot3 - PVT:940:virt:4TB:LPM operation failed by returning HSCLA2CF, HSCL365C SRC"s - Linux partition suspend timeout * RHEL8.4 - benchTableRepDMLAsyncBarrier regresses by 34% on RHEL8.4 on POWER9 compared to RHEL8.2 * [panic] call trace: ice_probe+0x238/0x10f0 [ice] * [ice, PTP] ice: fix GPIO 1PPS signal * Fix locality handling in the tpm_tis driver * [ice, PTP]: fix Tx queue iteration for Tx timestamp enablement * PCI passthrough with NVidia GPU Invalid device 0003:01:00.0 iommu_group file /sys/bus/pci/devices/0003:01:00.0/iommu_group is not a symlink * [DELL 8.4 BUG] - System Hangs at Dell Logo When Boot to OS * RHEL8.4 - kernel: Fix hanging ioctl caused by wrong msg counter * kernel: get_timespec64 does not ignore padding in compat syscalls * [mlx5] eth0: hw csum failure * xlog_grant_head_wait does not return and system hangs * panic while breaking a lease/delegation after user mode helper invocation * Lockd invalid cast to nlm_lockowner * [xfstests generic/388] XFS: Assertion failed: 0, file: fs/xfs/xfs_mount.c, line: 1218 Enhancement: * [Intel 8.5 FEAT] ice: Enable PTP Support * [Intel 8.5 FEAT] ice: Enable GPIO/SDP Support 4.
