  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\naccel/amdxdna: Fix use-after-free in amdxdna_gem_dmabuf_mmap()\n\nWhen vm_insert_pages() fails, the error path calls vma-\u003evm_ops-\u003eclose(vma)\nwhich internally calls drm_gem_vm_close() → drm_gem_object_put(),\nreleasing the GEM object reference acquired at the start of the function.\nHowever, the close_vma label then falls through to put_obj, which calls\ndrm_gem_object_put() a second time on the same object.\n\nIf the first put releases the last reference, the object is freed and the\nsecond put accesses freed memory, causing a use-after-free.\n\nFix by returning directly from close_vma instead of falling through to\nput_obj, since the close handler already performs all necessary cleanup\nincluding the object put.",
