Published Oct 18, 2022
·
Updated

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 clsroute 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)
