Hey folks,

I just released a tool to mitigate CVE-2026-31431 using eBPF.

If you're tired of manually configuring seccomp profiles across your clusters, this might be for you. It's deployed as a simple DaemonSet and handles the exploit attempt based on your kernel version:

• On supported kernels: It prevents the application from opening sockets with AF_ALG.
• On older kernels: It sends a SIGKILL to the process attempting the call.

All it takes is a single DaemonSet deployment. Check it out here:

Hope you find it useful! :-)
