Summary: An update for kernel 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. 2. Relevant releases/architectures: Red Hat CodeReady Linux Builder EUS (v. 8.4) - aarch64, ppc64le, x86_64 Red Hat Enterprise Linux BaseOS EUS (v.8.4) - aarch64, noarch, ppc64le, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. The following packages have been upgraded to a later upstream version: kernel (4.18.0). Security Fix(es): * A use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588) * Information leak in the IPv6 implementation (CVE-2021-45485) * Information leak in the IPv4 implementation (CVE-2021-45486) * Incomplete cleanup of multi-core shared buffers (aka SBDR) (CVE-2022-21123) * Incomplete cleanup of microarchitectural fill buffers (aka SBDS) (CVE-2022-21125) * Incomplete cleanup in specific special register write operations (aka DRPW) (CVE-2022-21166) 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): * DR, Ignore modify TTL if ConnectX-5 doesn't support it (BZ#2075549) * execve exit tracepoint not called (BZ#2106663) * Unable to boot RHEL-8.6 on Brazos max. config (Install is success) (BZ#2107475) * "vmcore failed, _exitcode:139" error observed while capturing vmcore during fadump after memory remove. incomplete vmcore is captured. (BZ#2107490) * soft lockups under heavy I/O load to ahci connected SSDs (BZ#2110773) * Allow substituting custom vmlinux.h for the build (BZ#2116407) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5.
