(RHSA-2022:6983) Important: kernel security, bug fix, and enhancement update

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)
