CVE 설명

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.

CVE 정보

관련 약점

CWE-ID 약점 이름 출처
CWE-190 Integer Overflow or Wraparound
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
