  "title": "cifs: fix cifsFileInfo leak on kmalloc failure in deferred close drain paths",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  cifs: fix cifsFileInfo leak on kmalloc failure in deferred close drain paths  In cifs_close_deferred_file(), cifs_close_all_deferred_files(), and cifs_close_deferred_file_under_dentry(), when a pending deferred close is cancelled via cancel_delayed_work(), the subsequent kmalloc_obj() to add the file to the local processing list may fail under memory pressure. The loop breaks immediately, but the cancelled work is no longer pending (it would have called _cifsFileInfo_put()), and the cfile is never added to file_head for processing.  The cifsFileInfo reference and the open server handle both leak.  Fix by saving the cfile that failed allocation in a local variable, breaking as before, and calling _cifsFileInfo_put() on it after releasing the lock.  Any files later in the iteration are unaffected since their deferred work is still pending and will fire normally.",
