About this tag
CVE-2026-31495 is a Linux kernel vulnerability in the ctnetlink path that allowed malformed netlink values to reach conntrack logic before proper policy validation. The flaw involved trust-boundary failures in the networking stack, where invalid state, mask, and shift inputs were not rejected early enough. The fix moves validation into the netlink policy layer, enabling fast failure and meaningful extack errors. This CVE highlights the importance of robust input validation in kernel networking components.

    CVE-2026-31495: Linux ctnetlink Netlink Policy Validation Fix

    CVE-2026-31495 is a reminder that some of the most consequential Linux kernel flaws are not dramatic memory-corruption headlines but quiet trust-boundary failures in the networking stack. In this case, the kernel’s ctnetlink path accepted malformed netlink values that should have been rejected...
