starxsky/cve-2026-31431Provides attack source code and sniffing tools for CVE-2026-31431, a kernel vulnerability, along with mitigation instructions including disabling the algif_aead module and seccomp rules.
"Copy Faill" CVE-2026-31431 Archive and Analysis.
# 禁用内核模块
echo "install algif_aead /bin/false" > /etc/modprobe.d/disable-algif-aead.conf
# 卸载已加载模块
rmmod algif_aead 2>/dev/null
注：针对静态编译进内核的系统（例如：RHEL/CentOS/Rocky Linux/AlmaLinux 8, 9, 10 三代产品），此缓解措施可能无法生效，建议更新官方内核补丁。
# 验证
python3 -c 'import socket; s=socket.socket(38,5,0); (s.bind(("aead", "authencesn(hmac(sha256),cbc(aes))")) or print("未缓解")) if s else None' 2>/dev/null || echo "已缓解"
4. 容器环境加固
通过 seccomp 禁止 AF_ALG socket 创建（family=38）：
"syscalls": [{ "names": ["socket"], "action": "SCMP_ACT_ERRNO", "args": [{"index": 0, "value": 38, "op": "SCMP_CMP_EQ"}]}]
