CVE-2018-9568: Incorrect Type Cast

First published: Mon Dec 03 2018(Updated: )

A possible memory corruption due to a type confusion was found in the Linux kernel in the sk_clone_lock() function in the net/core/sock.c. A possibility of local escalation of privileges cannot be fully ruled out for a local unprivileged attacker.
