CVE-2024-50004

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: update DML2 policy EnhancedPrefetchScheduleAccelerationFinal DCN35

[WHY & HOW] Mismatch in DCN35 DML2 cause bw validation failed to acquire unexpected DPP pipe to cause grey screen and system hang. Remove EnhancedPrefetchScheduleAccelerationFinal value override to match HW spec.

(cherry picked from commit 9dad21f910fcea2bdcff4af46159101d7f9cd8ba)
