Summary
Red Hat Security Advisory: kpatch-patch security update
Notes
Topic
An update for kpatch-patch 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
This is a kernel live patch module which is automatically loaded by the RPM post-install script to modify the code of a running kernel.
Security Fix(es):
* kernel: Rogue cross-process SSBD shutdown. Linux scheduler logical bug allows an attacker to turn off the SSBD protection. (CVE-2020-10766)
* kernel: Indirect Branch Prediction Barrier is force-disabled when STIBP is unavailable or enhanced IBRS is available. (CVE-2020-10767)
* kernel: Indirect branch speculation can be enabled after it was force-disabled by the PR_SPEC_FORCE_DISABLE prctl command. (CVE-2020-10768)
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.
