Title:RHSA-2022:6437: kernel-rt security and bug fix update (Moderate)
Description:The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

  • Incomplete cleanup of multi-core shared buffers (aka SBDR) (CVE-2022-21123)

  • Incomplete cleanup of microarchitectural fill buffers (aka SBDS) (CVE-2022-21125)

  • Incomplete cleanup in specific special register write operations (aka DRPW) (CVE-2022-21166)

    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):

  • The latest RHEL 8.6.z3 kernel changes need to be merged into the RT source tree to keep source parity between the two kernels. (BZ#2111112)
