CVE-2025-22093 is a Linux kernel vulnerability in the AMD display driver (drm/amd/display) where a NULL pointer dereference occurs if the ASIC does not support DMUB. The flaw arises because the code dereferences a NULL pointer when it assumes DMUB support without proper checks, leading to a kernel crash (NULL pointer dereference). This issue has been fixed by adding a check for the DMUB service pointer before use.
