A null pointer dereference occurs in the AMDGPU DRM driver when the SDMA block is disabled and buffer functions are not initialized. This fault can trigger a kernel panic, resulting in a system reboot and loss of availability. The flaw originates from a use of an uninitialized pointer and corresponds to CWE‑476.

All releases of the Linux kernel that incorporate the AMDGPU DRM driver are potentially affected, regardless of distribution. The specific kernel versions are not listed, so any build preceding the patch that contains this code path should be considered vulnerable.

The EPSS score is not available and the vulnerability is not listed in the CISA KEV catalog, indicating no known active exploitation. Based on the description, it is inferred that the attack vector requires local privileged access, such as sending crafted commands to the AMDGPU device or exploiting a privileged application. If an attacker gains such access, the kernel panic can be triggered, leading to a denial of service.
