CWE-190

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.

Affected configurations

• linux linux kernel (<= 3.14.3) • debian debian linux 7.0 • canonical ubuntu linux 10.04 • canonical ubuntu linux 12.04 • canonical ubuntu linux 13.10 • oracle linux 6 • oracle linux 7
