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: tun: avoid double free in tun_free_netdev (CVE-2022-4744) * ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF (CVE-2023-0266) * 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): * AlmaLinux9.0 - zfcp: fix missing auto port scan and thus missing target ports (BZ#2127880) * Cgroups_v2, when creating new cgroup/container, resets the cpu affinity masks for all usr processes on the system. (BZ#2143766) * AlmaLinux9.0 - boot: Add secure boot trailer (BZ#2151528) * kernel-rt-debug: WARNING: possible circular locking dependency detected (&n->list_lock->&p->pi_lock->&lock->wait_lock) (BZ#2160614) * Support cpuset.sched_load_balance by changing default CPUset directory structure (BZ#2161105) * AlmaLinux9.0 - s390/kexec: fix ipl report address for kdump (BZ#2166903) * libgpiod doesn't seem to work with Interphase gpiochip (BZ#2166956) * Azure AlmaLinux9 scsi: storvsc: Fix swiotlb bounce buffer leak in confidential VM (BZ#2170227) Enhancement(s): * IBM 9.2 FEAT: Upgrade the QETH driver to latest from upstream, e.g. kernel 6.0 (BZ#2166304) * Intel 9.2 FEAT SPR CPU: AMX: Improve the init_fpstate setup code (BZ#2168382)
