A local privileged user could use this to further escalate their privileges. (CVE-2022-41804) It was discovered that some 3rd Generation Intel(R) Xeon(R) Scalable processors did not properly restrict access in some situations. A local privileged attacker could use this to obtain sensitive information. (CVE-2023-23908) Update Instructions: Run `sudo pro fix USN-6286-1` to fix the vulnerability. The problem can be corrected by updating your system to the following package versions: intel-microcode - 3.20230808.0ubuntu0.16.04.1+esm1 Available with Ubuntu Pro (Infra-only): https://ubuntu.com/pro
