CVE-2022-21166

Published: 15 June 2022

Incomplete cleanup in specific special register write operations for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

From the Ubuntu security team

It was discovered that some Intel processors did not properly perform cleanup during specific special register write operations. A local attacker could possibly use this to expose sensitive information.

Priority

CVSS 3 base score: 5.5
