Hi, these two patches fix a crash in the tty driver when a user specifies an invalid console like 'console=tty3000'. The first patch adds a check to tty_driver_lookup_tty(), the second one prevents that such a console gets registered in the vt driver. Changes in v2: - trim commit message in first patch - add second patch as suggested by Jiri Slaby Sven Schnelle (2): tty: fix out-of-bounds access in tty_driver_lookup_tty() tty/vt: prevent registration of console with invalid number drivers/tty/tty_io.c | 8 +++++--- drivers/tty/vt/vt.c | 6 ++++++ 2 files changed, 11 insertions(+), 3 deletions(-) -- 2.34.1
