(RHSA-2022:7134) Important: kernel-rt security and bug fix update

Description

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): * kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588) * kernel: information leak in scsi_ioctl() (CVE-2022-0494) * Kernel: A kernel-info-leak issue in pfkey_register (CVE-2022-1353) * hw: cpu: AMD: RetBleed Arbitrary Speculative Code Execution with Return Instructions (CVE-2022-23816, CVE-2022-29900) * hw: cpu: AMD: Branch Type Confusion (non-retbleed) (CVE-2022-23825) * hw: cpu: Intel: RetBleed Arbitrary Speculative Code Execution with Return Instructions (CVE-2022-29901) 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): * [rhel8-rt] BUG: using __this_cpu_add() in preemptible [00000000] - caller is __mod_memcg_lruvec_state+0x69/0x1c0 (BZ#2122600) * The latest RHEL 8.6.z4 kernel changes need to be merged into the RT source tree to keep source parity between the two kernels. (BZ#2125396)
