093903a8d4c05d1adff79895a52a3e3009ff07a7 - tty: Avoid leaving dangling pointers in tty_drop_ctty()

Mon, 23 Mar 2026 16:22:48 +0100

tty: Avoid leaving dangling pointers in tty_drop_ctty()The TIOCNOTTY handler detaches the calling process from its controllingterminal. It clears the link from the session to the tty, but not thepointers from the tty to the session and process group. This means thatsess_release() doesn't call tty_rel_sess(), and that pgdelete() doesn'tcall tty_rel_pgrp(), so the pointers are left dangling.Fix this by clearing pointers in tty_drop_ctty(). Add a standaloneregression test.Approved by: soSecurity: FreeBSD-SA-26:10.ttySecurity: CVE-2026-5398Reported by: Nicholas Carlini Reviewed by: kib, kevansFixes: 1b50b999f9b5 ("tty: implement TIOCNOTTY")Differential Revision: https://reviews.freebsd.org/D56046 List of files: /freebsd/tests/sys/kern/tty/Makefile

tests: kern: add some porch(1)-based tty testsIf sysutils/porch is installed, we'll do some basic testing of ttybehavior. The existing tests primarily cover ICANON-related processingand corner cases that have been fixed somewhat recently, but Ianticipate growing this out a bit in due time.Reviewed by: ngieDifferential Revision: https://reviews.freebsd.org/D46806 List of files: /freebsd/tests/sys/kern/tty/Makefile
