https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=202540 Bug ID: 202540 Summary: libteken assert() fail on teken.c line 231 Product: Base System Version: 11.0-CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: kcwu@csie.org Because syscons (a kernel driver) uses libteken, an assertion failure in libteken would result in kernel panic. How to reproduce: To reproduce the assertion reliably, I modified src/sys/teken/stress/teken_stress.c to take input from stdin. $ echo -e '\e[?6h\e[5r\e[65533H' | ./teken_stress Assertion failed: (t->t_cursor.tp_row >= t->t_originreg.ts_begin), function teken_input_char, file /usr/src/sys/teken/teken.c, line 231. Abort trap (core dumped) This issue is found by afl-fuzz This is similar but different case to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=202326 . Please let me know if you want me report in the same tracking bug. -- You are receiving this mail because: You are the assignee for the bug.
