In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: Using uninitialized value *size when calling amdgpu_vce_cs_reloc

Initialize the size before calling amdgpu_vce_cs_reloc, such as case 0x03000001.
V2: To really improve the handling we would actually
need to have a separate value of 0xffffffff.(Christian)

A vulnerability was found in the Linux kernel's amdgpu driver in the amdgpu_vce_ring_parse_cs() function where the size variable is initialized with a pointer that may not be properly set before use. This issue could lead to unpredictable behavior in the system.
