kernel: tty: add the option to have a tty reject a new ldisc

A vulnerability was found in the Linux kernel's TTY subsystem, where the option to reject a new ldisc was improperly implemented, which can lead to a situation where the conwrite routine is called while holding a spinlock, potentially causing a sleep operation in an invalid context...

kernel: tty: Fix out-of-bound vmalloc access in imageblit

A vulnerability was found in the Linux kernel's tty subsystem within the imageblit function when a userspace program performs an ioctl operation with the FBIOPUTVSCREENINFO command, passing a fbvarscreeninfo structure with limited fields. If the structure’s values remain unchanged from a previous...
