  "title": "misc: fastrpc: fix use-after-free race in fastrpc_map_create",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  misc: fastrpc: fix use-after-free race in fastrpc_map_create  fastrpc_map_lookup returns a raw pointer after releasing fl-\u003Elock. The caller fastrpc_map_create then calls fastrpc_map_get (kref_get_unless_zero) on this unprotected pointer. A concurrent MEM_UNMAP can free the map between the lock release and the kref operation, resulting in a use-after-free on the freed slab object.  Restore the take_ref parameter to fastrpc_map_lookup so the reference is acquired atomically under fl-\u003Elock before the pointer is exposed to the caller.",
