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

drm/amdgpu: Fix memory leak in amdgpu acpi enumerate xcc()

In amdgpu acpi enumerate xcc(), if amdgpu acpi dev init() returns -ENOMEM, the function returns directly without releasing the allocated xcc info, resulting in a memory leak.

Fix this by ensuring that xcc info is properly freed in the error paths.
