★ 总体评分：40分

■ 【总体评价】

提交仅包含变更日志而缺失核心修复代码，导致权限校验漏洞未修复且修复承诺未兑现
逻辑严重缺失且遗留高危安全漏洞，按规则强制限制在40分

■ 【详细分析】

• 1.语法逻辑 存在严重错误 ✕

diff中仅修改了debian/changelog文件，声明修复了SetLocked函数中的多路径校验问题，但完全缺失对应的src/dde-lock/lockworker.cpp源码修改，导致声明的修复逻辑未生效
潜在问题：核心修复代码缺失导致功能异常；changelog记录与实际代码状态不符导致版本管理混乱
建议：补充src/dde-lock/lockworker.cpp中LockWorker::setLocked函数的多路径校验逻辑实现代码

• 2.代码质量 存在严重问题 ✕

提交内容不完整，仅包含日志说明而无实质性代码变更，不符合规范的代码提交要求
潜在问题：代码审查无法验证修复效果；破坏了git提交的原子性和完整性
建议：将changelog与实际的C++源码修改合并为一个完整的提交

• 3.代码性能 无性能问题 ✓

变更日志的追加操作仅为字符串拼接，不涉及系统资源消耗或算法开销

• 4.代码安全 存在 1 个安全漏洞（高危1个） ✕

漏洞对比统计：新增漏洞 1 个，减少漏洞 0 个，持平 0 个
由于实际修复代码缺失，src/dde-lock/lockworker.cpp中的LockWorker::setLocked函数依然保留仅检查单一调用者路径的逻辑，存在被恶意调用者绕过校验的风险

• 安全漏洞1（高危）：权限校验绕过 在 src/dde-lock/lockworker.cpp 的 LockWorker::setLocked 函数中，原代码仅硬编码检查单一调用者路径（如/usr/bin/dde-lock），在软链接、不同安装路径等场景下，攻击者可通过构造特定路径的进程伪装合法调用者，绕过DBus身份校验执行锁屏或解锁操作，导致本地权限提升或拒绝服务 ——非常重要

• 建议：在LockWorker::setLocked函数中实现多路径遍历校验逻辑，将硬编码单路径改为包含/usr/bin/dde-lock、/usr/lib/deepin-daemon/dde-lock等可能路径的列表，并结合/proc/pid/exe的realpath进行严格匹配
