Summary
Red Hat Security Advisory: kernel-rt security and bug fix update

Notes

Topic
An update for kernel-rt is now available for Red Hat Enterprise Linux 8.4 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): * KVM: cmpxchg_gpte can write to pfns outside the userspace region (CVE-2022-1158) 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): * Multicast packets are not received by all VFs on the same port even though they have the same VLAN (BZ#2117027) * Backport use of a dedicate thread for timer wakeups (BZ#2127206) * Update RT source tree to the RHEL-8.4.z13 source tree. (BZ#2129948) * Cannot trigger kernel dump using NMI on SNO node running PAO and RT kernel [RT-8] (BZ#2139853)
