Summary

Important: kernel security and bug fix update

Details

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 [almalinux-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)

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
