The vulnerable code had existed for over a decade, but a seemingly unrelated change in 2025 removed a size limit that had unknowingly prevented it from being exploited. Once that guard disappeared, a dormant integer truncation bug became a reliable kernel memory corruption vulnerability.\nThe public proof-of-concept is equally impressive from a research perspective. It supports roughly 800 x86-64 kernel builds, avoids traditional heap grooming techniques, and demonstrates a deterministic path from a local user account to root by abusing a 16-bit Netlink length wraparound in the Open vSwitch datapath.\nI put together a deep technical analysis covering the vulnerability from the kernel internals upward, including the root cause, why it remained hidden for 13 years, how the exploit chain works, affected distributions, upstream fixes, and practical mitigation guidance.\n\ud83d\udd17 Read the full analysis:\nhttps://thecybersecguru.com/news/ovswrap-cve-2026-64531-linux-kernel-openvswitch-root-vulnerability/\nWhat are your thoughts on unprivileged user namespaces?
