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 Moderate. 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: information exposure in drivers/char/random.c and kernel/time/timer.c (CVE-2020-16166) 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-8.2.z#5 source tree (BZ#1873287) * optimization for delaying the freeing of empty slubs causes a NULL pointer dereference (BZ#1880502)
