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: use-after-free vulnerability in the perf_group_detach function of the Linux Kernel Performance Events (CVE-2023-2235)
  • kernel: netfilter: use-after-free in nf_tables when processing batch requests can lead to privilege escalation (CVE-2023-32233)
  • Kernel: bluetooth: Unauthorized management command execution (CVE-2023-2002)
  • kernel: OOB access in the Linux kernel’s XFS subsystem (CVE-2023-2124)
  • kernel: i2c: out-of-bounds write in xgene_slimpro_i2c_xfer() (CVE-2023-2194)
  • kernel: tls: race condition in do_tls_getsockopt may lead to use-after-free or NULL pointer dereference (CVE-2023-28466)

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):

  • [RT] Single Node Openshift cluster becomes unreachable after running less than 2 hours (BZ#2186853)
  • kernel-rt: update RT source tree to the latest AlmaLinux-9.2.z1 Batch (BZ#2188313)
