Weirdly, the mitigation does not seem to work under WSL2 (at least in Ubuntu 24.04).

    Linux wsl2 6.6.87.2-microsoft-standard-WSL2 ...
`modprobe algif_aead` errors out, but if I run the POC, it succeeds.

Outside of WSL2, the mitigation does appear to work though.

It's possible that the WSL kernel has that code compiled-in rather than as a loadable module. If they ship the kernel config somewhere, you could verify with

  zgrep CRYPTO_USER_API_AEAD /proc/config.gz /boot/config-*
It should show =m if it's a loadable module, and =y if it's compiled in.
