linux-stable.git/drivers/usb/serial, branch v3.2.67 Linux kernel stable tree USB: console: fix potential use after free 2015-02-20T00:49:36+00:00 Johan Hovold johan@kernel.org 2015-01-05T15:04:13+00:00 27e5ab9cfb34a9491599c1cc7785755b2c5cb512 commit 32a4bf2e81ec378e5925d4e069e0677a6c86a6ad upstream. Use tty kref to release the fake tty in usb_console_setup to avoid use after free if the underlying serial driver has acquired a reference. Note that using the tty destructor release_one_tty requires some more state to be initialised.
