Summary
Red Hat Security Advisory: kernel-rt security and bug fix update
Notes
Topic
An update for kernel-rt is now available for Red Hat Enterprise Linux 8.2 Extended Update Support.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
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 via PI futex state (CVE-2021-3347)
* 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):
* kernel-rt: update RT source tree to the latest RHEL-8.2.z8 Batch source tree (BZ#1916765)
