Summary: An update for kernel is now available for Red Hat Enterprise Linux 8. 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 (v. 8) - aarch64, ppc64le, x86_64 Red Hat Enterprise Linux BaseOS (v. 8) - 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). (BZ#2036888) Security Fix(es): * kernel: improper initialization of the "flags" member of the new pipe_buffer (CVE-2022-0847) * kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920) * kernel: local privilege escalation by exploiting the fsconfig syscall parameter leads to container breakout (CVE-2021-4154) * kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330) * kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS (CVE-2022-0435) * kernel: cgroups v1 release_agent feature may allow privilege escalation (CVE-2022-0492) * kernel: missing check in ioctl allows kernel memory read/write (CVE-2022-0516) * kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942) 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.
