In the Linux kernel before 6.4.12, amdgpucswaitallfences in drivers/gpu/drm/amd/amdgpu/amdgpucs.c has a fence use-after-free.

— MITRE

Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a fence use-after-free flaw in the amdgpucswaitallfences function in drivers/gpu/drm/amd/amdgpu/amdgpucs.c. By sending a specially crafted request, an authenticated attacker could exploit this vulnerability to gain elevated privileges.
