include/net/netfilter/nf_conntrack_extend.h in the netfilter subsystem in the Linux kernel before 3.14.5 uses an insufficiently large data type for certain extension data, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via outbound network traffic that triggers extension loading, as demonstrated by configuring a PPTP tunnel in a NAT environment.

Security readout for executives and security teams

CVE-2014-9715 is a Linux kernel netfilter flaw that can let a local user crash affected systems. The public description ties impact to denial of service, not data theft or remote takeover. Systems running kernels before 3.14.5 or unfixed vendor kernels need review. Exposure is most relevant on Linux hosts using affected kernel builds with netfilter connection tracking/NAT paths enabled. The bundle lists generic upstream Linux before 3.14.5 and vendor advisories from Debian, Red Hat, and Oracle, but does not enumerate every downstream package version. Schedule remediation through normal kernel patching, with higher priority for shared Linux infrastructure where local users could disrupt availability. No provided source supports emergency treatment for remote compromise or active exploitation. Mitigation focus: Apply vendor kernel updates that include the upstream 3.14.5 netfilter fix.; Prioritize multi-user systems, shared hosts, and systems relying on NAT or connection tracking.; Check Debian, Red Hat, Oracle, or other distribution advisories for supported fixed packages..
