Summary

Important: kernel-rt security and bug fix update

Details

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): * kernel: race condition in perf_event_open leads to privilege escalation (CVE-2022-1729) 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): * The latest AlmaLinux 8.6.z1 kernel changes need to be merged into the RT source tree to keep source parity between the two kernels. (BZ#2098244)

Vulnerability from cvelistv5 – Published: 2022-09-01 00:00 – Updated: 2024-08-03 00:16

Summary

A race condition was found the Linux kernel in perf_event_open() which can be exploited by an unprivileged user to gain root privileges. The bug allows to build several exploit primitives such as kernel address information leak, arbitrary execution, etc.

Severity

No CVSS data available.
