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. 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 in block/bfq-iosched.c related to bfq_idle_slice_timer_body (CVE-2020-12657) 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: hw: provide reporting and microcode mitigation toggle for CVE-2020-0543 / Special Register Buffer Data Sampling (SRBDS) (BZ#1827193) * kernel-rt: update RT source tree to the RHEL-8.2.z1 source tree (BZ#1816271)
