RHSA-2022:5267: Important: kernel-rt security and bug fix update
First published: Tue Jun 28 2022(Updated: )
The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.<br>Security Fix(es):<br><li> kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak (CVE-2022-1012)</li> <li> kernel: race condition in perf_event_open leads to privilege escalation (CVE-2022-1729)</li> <li> kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-1966)</li> <li> kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666)</li> 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.<br>Bug Fix(es):<br><li> kernel-rt: update RT source tree to the latest RHEL-9.0.z1 Batch (BZ#2089492)</li>
