Summary
Red Hat Security Advisory: microcode_ctl security update
Notes
Topic
An update for microcode_ctl is now available for Red Hat Enterprise Linux 9.
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 microcode_ctl packages provide microcode updates for Intel and AMD processors.
Security Fix(es):
* kernel: local privilege escalation on Intel microcode on Intel(R) Xeon(R) (CVE-2023-22655)
* kernel: Local information disclosure on Intel(R) Atom(R) processors (CVE-2023-28746)
* kernel: Local information disclosure in some Intel(R) processors (CVE-2023-38575)
* kernel: Possible Denial of Service on Intel(R) Processors (CVE-2023-39368)
* kernel: Local information disclosure on Intel(R) Xeon(R) D processors with Intel(R) SGX due to incorrect calculation in microcode (CVE-2023-43490)
* intel-microcode: Race conditions in some Intel(R) Processors (CVE-2023-45733)
* intel-microcode: Unexpected behavior in Intel(R) Core(TM) Ultra Processors (CVE-2023-46103)
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.
