Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 6.6.61 Description: The issue is related to the Linux kernel, where a problem with the `dmub psr enable()` function and Parade 08-01 TCON causes black screens and kernel WARNING traces at bootup and during fullscreen VA-API video. Disabling PSR-SU for this TCON resolves the symptoms. The estimated number of potentially affected devices is not specified. Recommendations: For Linux kernel versions prior to 6.6.61, update to version 6.6.61 or later to resolve the issue. As a temporary workaround, consider disabling PSR-SU on Parade 08-01 TCON to minimize the risk of exploitation.
