Summary: An update for kernel is now available for Red Hat Enterprise Linux 9. 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. 9) - aarch64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux AppStream (v. 9) - aarch64, noarch, ppc64le, s390x, x86_64 Red Hat Enterprise Linux BaseOS (v. 9) - aarch64, noarch, ppc64le, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak (CVE-2022-1012) * kernel: race condition in perf_event_open leads to privilege escalation (CVE-2022-1729) * kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-1966) * kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666) 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): * make SHA512_arch algos and CRYPTO_USER built-ins (BZ#2072643) * SR-IOV performance > 50% degradation (BZ#2074830) * fix data corruption caused by dm-integrity (BZ#2082187) * SCTP client-side peeloff issues [rhel-9] (BZ#2084044) * TCP connection fails in a asymmetric routing situation (BZ#2085480) * Fails to boot Multiple RT VMs each with multiple vCPUs (BZ#2086963) * spec: Fix separate tools build (BZ#2090852) * call traces related to eeh_pseries observed and vmcore is not captured, when kdump is triggered (BZ#2092255) * Mark ThunderX NIC driver as unmaintained (BZ#2092638) 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.
