kernel: use-after-free in read in vt_do_kdgkb_ioctl

A flaw was found in the Linux kernel. A use-after-free was found in the way the console subsystem was using ioctls KDGKBSENT and KDSKBSENT. A local user could use this flaw to get read memory access out of bounds. The highest threat from this vulnerability is to data confidentiality...

kernel: tty: n_gsm: fix deadlock and link starvation in outgoing data path
