The pppol2tp_xmit function in drivers/net/pppol2tp.c in the L2TP implementation in the Linux kernel before 2.6.34 does not properly validate certain values associated with an interface, which allows attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via vectors related to a routing change.

Security readout for executives and security teams

CVE-2010-2495 is a Linux kernel L2TP flaw that can crash affected systems. The issue is in pppol2tp_xmit before Linux 2.6.34, where interface-related values were not properly validated. The documented business risk is service disruption, especially on legacy systems or appliances still using old kernel branches with L2TP enabled. Exposure is most likely in legacy Linux systems, embedded products, network appliances, or vendor kernels derived from pre-2.6.34 code and using L2TP/PPPoL2TP. Modern maintained distributions are less likely affected if vendor kernel updates were applied. Treat this as a legacy resilience issue rather than an active-crisis item. Prioritize internet-facing or business-critical systems that use L2TP, and any unsupported appliances where kernel patch status is uncertain. Mitigation focus: Apply the relevant vendor kernel update for affected Linux distributions.; Upgrade kernels derived from vulnerable pre-2.6.34 L2TP code.; Review Ubuntu, SUSE, Red Hat, and kernel advisories for package-specific fixes..
