CVE-2013-4162: Medium severity Linux Linux kernel vulnerability
Last updated 24 July 2024
Other sources
Linux kernel built with IPv6 networking is vulnerable to a crash while sending data as a single datagram over IPv6 socket when UDPCORK option set. UDPCORK enables accumulating data and sending it as a single datagram.
An unprivileged user/program could use this flaw to crash the kernel, resulting in local DoS.

The udpv6pushpendingframes function in net/ipv6/udp.c in the IPv6 implementation in the Linux kernel through 3.10.3 makes an incorrect function call for pending data, which allows local users to cause a denial of service (BUG and system crash) via a crafted application that uses the UDPCORK option in a setsockopt system call.
