ip_nat_pptp in the PPTP NAT helper (netfilter/ip_nat_helper_pptp.c) in Linux kernel 2.6.14, and other versions, allows local users to cause a denial of service (memory corruption or crash) via a crafted outbound packet that causes an incorrect offset to be calculated from pointer arithmetic when non-linear SKBs (socket buffers) are used.

Security readout for executives and security teams

This is an old Linux kernel denial-of-service flaw in the PPTP NAT helper. A local user able to send a crafted outbound packet could trigger memory corruption or a crash. The business risk is mainly availability on legacy Linux systems using affected kernel code, not confirmed data theft or remote compromise. Exposure is most plausible on legacy Linux systems running affected 2.6-era kernels with PPTP NAT helper functionality present or enabled. The source bundle does not provide complete vendor, distribution, or fixed-version coverage. Treat this as a legacy-platform availability risk. Prioritize internet-edge or shared systems that still run old Linux kernels and provide PPTP NAT services. Modern, supported Linux fleets are less likely to be exposed, but unsupported systems should be removed or updated. Mitigation focus: Inventory systems running legacy Linux 2.6-era kernels.; Review vendor advisories and kernel commit guidance for CVE-2006-0037 fixes.; Apply supported vendor kernel updates where affected systems remain in service..
