CVE-2022-49969

Name of the Vulnerable Software and Affected Versions Linux kernel versions 5.4.0-54 through 5.4.0-162 Linux kernel versions 5.10.142-1 through 5.10.176-1 Linux kernel versions 5.15.0-33 through 5.15.0-70

Description A flaw exists in the optc1 enable optc clock() function of the Linux kernel due to incomplete cleanup of temporary or auxiliary resources. Specifically, within the drm/amd/display component, the OPC underflow bit is not cleared before the ODM clock is disabled. Once the ODM clock is turned off, the underflow bit remains set and cannot be cleared, which may impact the confidentiality, integrity, and availability of protected information.

Recommendations Update Linux kernel versions 5.4.0-54 through 5.4.0-162 to a patched release. Update Linux kernel versions 5.10.142-1 through 5.10.176-1 to a patched release. Update Linux kernel versions 5.15.0-33 through 5.15.0-70 to a patched release.
