Title:RHSA-2021:1070: 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: out-of-bounds read in libiscsi module (CVE-2021-27364)

  • kernel: heap buffer overflow in the iSCSI subsystem (CVE-2021-27365)

  • kernel: iscsi: unrestricted access to sessions and handles (CVE-2021-27363)

    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):

  • RHEL7.9 Realtime crashes due to a blocked task detection. The blocked task is stuck in unregister_shrinker() where multiple tasks have taken the shrinker_rwsem and are fighting on a dentry's d_lockref lock rt_mutex. [kernel-rt] (BZ#1935557)

  • kernel-rt: update to the latest RHEL7.9.z5 source tree (BZ#1939220)
