(RHSA-2022:8974) 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: KVM: cmpxchg_gpte can write to pfns outside the userspace region (CVE-2022-1158) * kernel: openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size() (CVE-2022-2639) * kernel: watch queue race condition can lead to privilege escalation (CVE-2022-2959) * kernel: nfsd buffer overflow by RPC message over TCP with garbage data (CVE-2022-43945) * hw: cpu: incomplete clean-up of multi-core shared buffers (aka SBDR) (CVE-2022-21123) * hw: cpu: incomplete clean-up of microarchitectural fill buffers (aka SBDS) (CVE-2022-21125) * hw: cpu: incomplete clean-up in specific special register write operations (aka DRPW) (CVE-2022-21166) * 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: Post-barrier Return Stack Buffer Predictions (CVE-2022-26373) * 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): * kernel-rt: update RT source tree to the latest RHEL-9.0.z5 Batch (BZ#2137580) * [DELL EMC 9.0-RT BUG] System is not booting into RT Kernel with perc12 [kernel-rt] (BZ#2139864)
