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 in unix_stream_sendpage (CVE-2023-4622)

  • kernel: race condition in VT_RESIZEX ioctl when vc_cons[i].d is already NULL leading to NULL pointer dereference (CVE-2020-36558)

  • kernel: bluetooth: Unauthorized management command execution (CVE-2023-2002)

  • kernel: net/sched: sch_hfsc UAF (CVE-2023-4623)

  • kernel: irdma: Improper access control (CVE-2023-25775)

Bug Fix(es):

  • kernel-rt: Update RT source tree to the latest RHEL-7.9z30 batch [rhel-7.9.z] (JIRA:RHEL-26440)

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.
