Alias CVE-2021-20219
Rohit Keshri 2021-02-02 17:24:43 UTC Depends On 1924152, 1924153
Rohit Keshri 2021-02-02 17:28:38 UTC Depends On 1909882
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.
