kernel: Double free in the inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c

The inetcskclonelock function in net/ipv4/inetconnectionsock.c in the Linux kernel allows attackers to cause a denial of service double free or possibly have unspecified other impact by leveraging use of the accept system call. An unprivileged local user could use this flaw to induce kernel memor...
