drm/xe: Fix dma-buf attachment leak in xe_gem_prime_import()_CVE-2026-46201

{
    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe: Fix dma-buf attachment leak in xe_gem_prime_import()\n\nWhen xe_dma_buf_init_obj() fails, the attachment from\ndma_buf_dynamic_attach() is not detached. Add dma_buf_detach() before\nreturning the error. Note: we cannot use goto out_err here because\nxe_dma_buf_init_obj() already frees bo on failure, and out_err would\ndouble-free it.\n\n(cherry picked from commit a828eb185aac41800df8eae4b60501ccc0dbbe51)",
