An update is available for kernel-rt.
This update affects Rocky Linux 8.
A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE list
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: netfilter: use-after-free in nf_tables when processing batch requests can lead to privilege escalation (CVE-2023-32233)

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):

  • smpboot: Scheduler frequency invariance went wobbly, disabling! (BZ#2188316)

  • Crash: kernel BUG at kernel/locking/rtmutex.c:1338! (BZ#2188722)

  • kernel-rt: update RT source tree to the Rocky Linux-8.8.z0 source tree. (BZ#2196667)
