To see if the vulnerable module is still loaded:
```
python3 -c 'import socket; s = socket.socket(socket.AF_ALG, socket.SOCK_SEQPACKET, 0); s.bind(("aead","authencesn(hmac(sha256),cbc(aes))")); print("algif_aead probably successfully loaded, mitigation not effective; remove again with: rmmod algif_aead")'
```
If it errors out, mitigation applied. If it prints, “algif_aead probably successfully loaded, mitigation not effective; remove again with: rmmod algif_aead” that module is still available.
Not sure if you saw my other posts on this. I was figuring things out yesterday. Still manually applying mitigation on systems that do not yet have a patched kernel update available with:
```
sudo sh -c "echo 'install algif_aead /bin/false' > /etc/modprobe.d/disable-algif.conf"
sudo rmmod algif_aead
```
