Title:RHSA-2021:2169: kernel-rt security and bug fix update (Important)
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):

  • kernel: userspace applications can misuse the KVM API to cause a write of 16 bytes at an offset up to 32 GB from vcpu->run (CVE-2021-3501)

  • kernel: nitro_enclaves stale file descriptors on failed usercopy (CVE-2021-3543)

    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 RHEL-8.4.z0 source tree (BZ#1957489)
  • Family:unixClass:patch
