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):
- posix cpu timer use-after-free may lead to local privilege escalation (CVE-2022-2585)
- Unprivileged users may use PTRACE_SEIZE to set PTRACE_O_SUSPEND_SECCOMP option (CVE-2022-30594)
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):
- Update RT source tree to the latest AlmaLinux-9.0.z4 Batch (BZ#2123498)
