Summary
Red Hat Security Advisory: linux-firmware security update
Notes
Topic
An update for linux-firmware is now available for Red Hat Enterprise Linux 9.2 Extended Update Support.
Red Hat Product Security has rated this update as having a security impact of Low. 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 linux-firmware packages contain all of the firmware files that are required by various devices to operate.
Security Fix(es):
* kernel: hw:amd:IOMMU improperly handles certain special address leading to a loss of guest integrity (CVE-2023-20584)
* kernel: hw: amd:Incomplete system memory cleanup in SEV firmware corrupt guest private memory (CVE-2023-31356)
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.
