CVE-2014-3144 describes an integer underflow vulnerability in the Linux kernel's BPF filter implementation (specifically BPF_S_ANC_NLATTR and BPF_S_ANC_NLATTR_NEST extensions) affecting versions through 3.14.3, including Canonical, Debian, and Oracle distributions. This flaw allows local users to trigger a denial of service (system crash) through crafted BPF instructions. With a CVSS score of 4.9 (AV:L/AC:L/Au:N/C:N/I:N/A:C), it is a low-severity vulnerability requiring local access and low attack complexity to achieve a complete system availability impact. There is no known active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or KEV listing, and community discussion and media coverage are minimal.
