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

tty: abort break signalling on hangup

The break ioctls can race with hangup and end up calling into a tty driver for a device that is already gone or powered down.

Drivers must handle this race, but TCSBRK and TCSBRKP should still be aborted to avoid calling back into the driver after a user-controlled timeout (possibly even after the tty has been reopened).

Note that drivers should disable any break state on shutdown so just return on hangup (calling break_ctl() again is racy and will most likely fail for drivers handling the race).
