| Rohit Keshri | 2021-02-02 18:29:29 UTC | Doc Text | A denial-of-service vulnerability was found in n_tty_receive_char_special in drivers/tty/n_tty.c of the Linux kernel. In this flaw a local attacker with a normal user privilege could delay the loop (due to a changing ldata->read_head, and a missing sanity check) and cause a threat to the system availability. | |
