The vulnerability allows a local user to crash the kernel.

The vulnerability exists due to a use-after-free error in drivers/gpu/drm/amd/amdgpu/amdgpu_hmm.c. A local user can send a single amdgpu_gem_userptr_ioctl to the AMDGPU DRM driver on any ASICs with an invalid address and size and perform a denial of service (DoS) attack.
