CVE-2024-49972

CVE-2024-49972 affects the Linux kernel DRM-AMD display path. The issue arises when creating DML memory during DC state changes: if the DML memory allocation fails, previously allocated memory was not deallocated, leaving an uninitialized, non-NULL structure. The documented fix deallocates the me...
