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 eventpoll.c may lead to escalation of privilege (CVE-2020-0466)

  • kernel: Integer overflow in Intel® Graphics Drivers (CVE-2020-12362)

  • kernel: SCSI target (LIO) write to any block on ILO backstore (CVE-2020-28374)

  • kernel: DoS by corrupting mountpoint reference counter (CVE-2020-12114)

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):

  • kernel-rt: update RT source tree to the latest RHEL-8.2.z9 Batch source tree (BZ#1949685)
