Description
In the Linux kernel, the following vulnerability has been resolved:
staging: greybus: uart: fix tty use after free
User space can hold a tty open indefinitely and tty drivers must not
release the underlying structures until the last user is gone.
Switch to using the tty-port reference counter to manage the life time
of the greybus tty state to avoid use after free after a disconnect.
