Hi @dmc_dtc,
Great work!

We're in the same boat here with no official patches yet. Can you confirm if the PoC actually works on OpenVZ 7? I haven't been able to find any documentation or guide on how to compile or test it. Do you happen to have the steps?

I wanted to check my system's vulnerability based on this article ( https://linuxjust4u.com/linux/ghostlock-cve-2026-43499-linux -futex-root-exploit-fix/), which mentions that running grep CONFIG_FUTEX_PI /boot/config-$(uname -r) should return CONFIG_FUTEX_PI=y.

Interestingly, I get that output on my AlmaLinux 9 hosts, but it returns nothing on OpenVZ 7. I suspect it might just be that the kernel config file isn't stored in /boot/ on OVZ7 by default, rather than the kernel being immune.

Any insights on this would be highly appreciated. Thanks!
