Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/xe: Fix bo leak in xe_dma_buf_init_obj() on allocation failure<br /> <br /> When drm_gpuvm_resv_object_alloc() fails, the pre-allocated storage bo<br /> is not freed. Add xe_bo_free(storage) before returning the error.<br /> <br /> xe_dma_buf_init_obj() calls xe_bo_init_locked(), which frees the bo on<br /> error. Therefore, xe_dma_buf_init_obj() must also free the bo on its own<br /> error paths. Otherwise, since xe_gem_prime_import() cannot distinguish<br /> whether the failure originated from xe_dma_buf_init_obj() or from<br /> xe_bo_init_locked(), it cannot safely decide whether the bo should be<br /> freed.<br /> <br /> Add comments documenting the ownership semantics: on success, ownership<br /> of storage is transferred to the returned drm_gem_object; on failure,<br /> storage is freed before returning.<br /> <br /> v2: Add comments to explain the free logic.<br /> <br /> (cherry picked from commit 78a6c5f899f22338bbf48b44fb8950409c5a69b9)
