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

drm/xe: Fix dma-buf attachment leak in xe_gem_prime_import()

When xe_dma_buf_init_obj() fails, the attachment from

dma_buf_dynamic_attach() is not detached. Add dma_buf_detach() before

returning the error. Note: we cannot use goto out_err here because

xe_dma_buf_init_obj() already frees bo on failure, and out_err would

double-free it.

(cherry picked from commit a828eb185aac41800df8eae4b60501ccc0dbbe51) (NVD)
