    modprobe algif_aead
    modprobe: FATAL: Module algif_aead not found in directory /lib/modules/6.14.3-x86_64-linode168
Yet this kernel is vulnerable.

That would suggest that CRYPTO_USER_API_AEAD=y in your kernel config. You can disable it in that case by setting that to "n", recompiling your kernel, and putting the new kernel in place.

Indeed, no modprobe.d will help when the feature is compiled into the kernel ("=y") instead of compiled into a runtime-loadable module.
