  "details": "In the Linux kernel, the following vulnerability has been resolved:  fs: afs: revert mmap_prepare() change  Partially reverts commit 9d5403b1036c (\"fs: convert most other generic_file_*mmap() users to .mmap_prepare()\").  This is because the .mmap invocation establishes a refcount, but .mmap_prepare is called at a point where a merge or an allocation failure might happen after the call, which would leak the refcount increment.  Functionality is being added to permit the use of .mmap_prepare in this case, but in the interim, we need to fix this.",
