In the Linux kernel, the following vulnerability has been resolved:

cifs: fix potential oops in cifs_oplock_break

With deferred close we can have closes that race with lease breaks, and so with the current checks for whether to send the lease response, oplock_response(), this can mean that an unmount (kill_sb) can occur just before we were checking if the tcon->ses is valid. See below:

To fix this change the ordering of the checks before sending the oplock_response to first check if the openFileList is empty.
