CVE-2014-3144 Integer overflow in n/a

What is CVE-2014-3144?

CVE-2014-3144 is a medium-severity vulnerability in Canonical Ubuntu Linux, published on 11 May 2014. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 do not check whether a certain length value is sufficiently large, which allows local users to cause a denial of service (integer underflow and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr and __skb_get_nlattr_nest functions before the vulnerability was announced.
