- Summary
- drm/amdgpu: Fix memory leak in amdgpu_acpi_enumerate_xcc()
- Details
-
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.
Compile tested only. Issue found using a prototype static analysis tool and code review.
