{"schema":"threatline.record/2","record":{"id":"CVE-2026-98751","aliases":[],"summary":"tty: abort break signalling on hangup","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ntty: abort break signalling on hangup\n\nThe break ioctls can race with hangup and end up calling into a tty\ndriver for a device that is already gone or powered down.\n\nDrivers 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).\n\nNote 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).","categories":["Operating
