The nl_fib_input function in fib_frontend.c in the Linux kernel before 2.6.15 does not check for valid lengths of the header and payload, which allows remote attackers to cause a denial of service (invalid memory reference) via malformed fib_lookup netlink messages.

Security readout for executives and security teams

This is an old Linux kernel denial-of-service issue. Before Linux 2.6.15, malformed fib_lookup netlink messages could trigger an invalid memory reference in routing code, potentially crashing or disrupting affected systems. The sources do not provide a CVSS score or evidence of active exploitation. Exposure is mainly legacy Linux systems, embedded devices, appliances, or unsupported distributions still running kernels before 2.6.15 or vendor kernels missing the referenced fix. Treat this as a legacy exposure cleanup item unless vulnerable kernels still support critical services. Business impact is availability disruption, with urgency driven by whether old kernels remain in production. Mitigation focus: Identify systems running Linux kernels older than 2.6.15.; Apply vendor kernel updates or upgrade to a maintained kernel release.; Check Linux distribution advisories for backported fixes..
