alibabacloud-ecs-sec-kernel

alibabacloud-ecs-sec-kernel is a skill for Claude Code from aliyun/alibabacloud-ecs-troubleshoot-skills. It costs 233 tokens per session (3,834 once invoked), scanned B, original, Apache-2.0.

A Linux kernel security scanner that checks for known CVE vulnerabilities and can test whether they are exploitable. CVEs are public identifiers for reported security flaws; the tests need administrator access and can crash the system.

In plain words
What is it for?
Use it to scan kernels, verify individual CVEs, run proof-of-concept tests, and produce JSON security reports in an isolated test environment.
Why use it?
It helps determine whether a Linux server’s kernel contains specific local privilege-escalation flaws, where an ordinary user may gain administrator access.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

alibabacloud-ecs-sec-kernel scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

The scan reads SKILL.md. This mod also ships 5 executable files (__init__.py, __main__.py, bundle_python311.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

sec-kernel

Linux 内核 CVE 漏洞检测与 PoC 验证工具。88 个内核漏洞检测器，CTF 挑战模式验证。

Version: 1.4.1 (JSON-driven architecture)

触发场景

当以下场景出现时，务必主动调用此技能：

  • 检测 Linux 内核漏洞
  • 验证特定 CVE 是否可利用
  • 执行 PoC 三阶段验证（Prepare → Run → Post）
  • 内核安全评估或审计
  • 用户提到 "内核安全"、"CVE"、"提权漏洞"、"PoC" 等关键词
  • 需要判断当前内核版本是否存在已知漏洞
  • 执行本地提权（LPE）路径验证

⚠️ 安全声明

PoC 验证可能导致 kernel crash (panic/hang/deadlock)，建议在隔离的虚拟机/可快照环境中运行。 PoC 不会永久改写系统文件，不会进行持久化提权。所有临时修改均在 Post 阶段完整恢复。 使用本工具即表示您同意遵守 完整安全声明 中的所有条款。 违规使用需承担全部法律责任。

快速使用

# 从 skill 根目录执行：

# 需要 root 权限（sudo）

# 首次运行：编译 PoC 二进制 + 全量检测（推荐）
sudo python3 -m scripts --compile-poc --verbose

# 全量检测与 PoC 验证（poc-bin 已编译后）
sudo python3 -m scripts --verbose

# 单 CVE 验证
sudo python3 -m scripts --cve-id CVE-2026-31431 -v

# 列出所有检测器（无需 root）
python3 -m scripts --list-detectors

# 输出 JSON 格式报告
sudo python3 -m scripts --format json -v

CLI 参数

参数 类型 默认值 说明
--mode choice host 运行模式（仅 host，Linux 服务器环境）
--poc-output path ./workspace PoC 证据输出目录
--poc-timeout int 30 PoC 执行超时时间（秒）
--no-prepare flag off 跳过 Prepare 阶段
--no-post flag off 跳过 Post 阶段
--poc-user string nobody Run 阶段执行用户（降权执行）
--no-force-demote flag off 不强制降权到非特权用户
--compile-poc flag off 自动编译缺失的 PoC 二进制文件（plain 模式）
--output-dir path ./workspace 报告输出目录
--format choice markdown 报告格式（markdown / json）
--cve-id string - 仅检测指定 CVE
--config path - 配置文件路径
--verbose / -v flag off 详细输出
--list-detectors flag off 列出所有检测器（无需 root）

关键参数说明

默认行为: 所有在 kernel_cves.yaml 中 enabled: true 的 CVE 都会自动执行 PoC 验证，无需额外参数。唯一跳过 PoC 的条件是将 CVE 设置为 enabled: false。

--compile-poc: 当 poc-bin/ 目录下缺少对应 ELF binary 时，自动调用 poc-src/build.sh 编译。首次运行时必须使用此参数（poc-bin/ 不再随仓库分发，需从源码动态编译）。

Why: PoC 二进制从源码动态编译，避免在 git 中存储大量 ELF 文件。编译采用静态链接 + strip，确保跨发行版兼容。

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
