CVE-2017-8890

Published: 10 May 2017

The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux kernel through 4.10.15 allows attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call.

From the Ubuntu security team

It was discovered that a double-free vulnerability existed in the IPv4 stack of the Linux kernel. An attacker could use this to cause a denial of service (system crash).
