In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
tty: abort break signalling on hangup<\/p>\n
The break ioctls can race with hangup and end up calling into a tty
\ndriver for a device that is already gone or powered down.<\/p>\n
Drivers must handle this race, but TCSBRK and TCSBRKP should still be
\naborted to avoid calling back into the driver after a user-controlled
\ntimeout (possibly even after the tty has been reopened).<\/p>\n
Note that drivers should disable any break state on shutdown so just
\nreturn on hangup (calling break_ctl() again is racy and will most likely
\nfail for drivers handling the race).<\/p>\n","protected":false},"excerpt":{"rendered":"
