原因说明填写请参考下方表格(注意：版本是否受影响和版本的原因说明必须对应，例如master版本分支受影响，那原因说明只能是受影响对应的原因之一!)：
分支状态 |
原因说明 | 使用场景 |
|---|---|---|
| 受影响 | 正常修复 | 受影响且需要修复（包含升级版本修复）的漏洞； 受影响且已经修复的漏洞（历史修复PR也需要关联issue）； 若因特殊原因无法修复，应修改原因说明为【不修复-特殊原因】，并在安委会备案相关情况。 |
| 受影响 | 漏洞仍在分析中 | 已关注到相关漏洞，正在处理，未明确漏洞影响和修复方案。 |
| 受影响 | 暂不修复-暂无解决方案或补丁 | 当前没有可用的修复或补救措施。【影响性分析】中应包含有关为什么没有修复或补救措施的详细说明、上游相关PR等。 |
| 受影响 | 不修复-超出修复范围 | 没有漏洞的修复计划。当版本停维、软件包宣布生命周期终止或弃用使用。 |
| 受影响 | 不修复-特殊原因导致不再修复 | 如存在其他特殊情况不修复相关漏洞，或评估后无法升级修复，应在openEuler社区安全委员会例会进行说明备案。 【影响性分析】中应包含不发布修复的详细说明、特殊情况还应有安委会会议纪要。 |
| 不受影响 | 不受影响-组件不存在 | 软件不受影响，因为易受攻击的组件不在产品中。 |
| 不受影响 | 不受影响-已有内置的内联控制或缓解措施 | 内置的内联控制或缓解措施可防止攻击者利用漏洞 |
| 不受影响 | 不受影响-漏洞代码不能被攻击者触发 | 易受攻击的组件存在，并且该组件包含易受攻击的代码。但是，易受攻击的代码的使用方式使得攻击者无法进行任何预期的攻击。 |
| 不受影响 | 不受影响-漏洞代码不在执行路径 | 易受影响的代码在执行过程中不可访问，包括产品的非预期状态。产品不使用也不执行的组件。 |
| 不受影响 | 不受影响-漏洞代码不存在 | 产品不受影响，因为漏洞背后的代码在产品中不存在。与component_not_present不同的是，有问题的组件存在，但由于某种原因（例如安全的编译器选项）使漏洞的特定代码不存在于组件中。 |

补丁适配报告 (CVE-2026-78376)
1. backport-CVE-2026-78376.patch
- 状态: 适配成功 (status=adapted)
- 置信度: medium
适配冲突说明
适配说明
- 20/23 hunks failed direct apply (git apply --check) due to baseline context drift: baseline webkitgtk-2.36.3 uses Vector<JSValueRef,16>+reserveInitialCapacity+uncheckedAppend loop (not the patch's lambda-constructor form) and jsObjectCall body already uses arguments.data() (not the patch's arguments.span().data()). Adaptation: replaced Vector<JSValueRef,16> with MarkedJSValueRefArray (class exists in baseline at API/MarkedJSValueRefArray.h)
- std::span
-> WTF::Span (baseline deliberately vendored std::span as WTF::Span, project convention) - inlined a missing free helper unsafeMakeSpan (template returning WTF::Span, keeping the call site verbatim). 3 directly-applicable hunks preserved verbatim. Adapted patch applies cleanly to a fresh checkout (git apply --check PASS) and git diff --stat confirms 5 files changed, 318 insertions(+), 28 deletions(-).

1. backport-CVE-2026-78376.patch
- 状态: 适配成功 (status=adapted)
- 置信度: high
适配冲突说明
适配说明
- 11 of 23 hunks required context adaptation. Baseline uses reserveInitialCapacity+uncheckedAppend loop instead of lambda constructor for Vector<JSValueRef,16>
- baseline already has arguments.data() and FALLTHROUGH
- instead of arguments.span().data() and [[fallthrough]]. Two API substitutions: std::span→WTF::Span (baseline renames std::span to WTF::Span) and unsafeMakeSpan(ptr,size)→WTF::Span
(ptr,size) (unsafeMakeSpan does not exist in 2.38.2). 12 hunks applied directly without modification. Patch verified: git apply --check passes on clean baseline, git diff --stat confirms 5 files changed, 313 insertions, 28 deletions.

- 状态: 适配成功 (status=adapted)
- 置信度: high
适配冲突说明
适配说明
- Cross-version adaptation (webkitgtk-2.22.2 from 2018 vs WebKit 2026 patch). 3 core files modified, 2 test files skipped. APICallbackFunction.h: replaced Vector<JSValueRef,16>+reserveInitialCapacity+uncheckedAppend with MarkedJSValueRefArray(toGlobalRef(exec),...)+fill loop+ASSERT in call() and construct()
- changed argumentCount to arguments.size() in callback calls
- adapted from new JSC API (JSGlobalObject*/callImpl/ECMAMode::sloppy()) to old API (ExecState*/call/NotStrictMode). JSCallbackObjectFunctions.h: same Vector->MarkedJSValueRefArray replacement in construct() and call() template functions
- added include and copyright. JSCValue.cpp: changed jsObjectCall signature from const Vector
& to const JSValueRef*,size_t (std::span unavailable in 2.22.2) - replaced Vector
arguments with MarkedArgumentBuffer+MarkedJSValueRefArray in jscValueCallFunction - adapted globalObject->toJS(jsContext), unsafeMakeSpan->arguments.data(),arguments.size()
- updated 3 call sites (invoke_methodv, function_callv, constructor_callv). Test files (testapi.cpp, TestJSC.cpp) skipped: use APIs unavailable in 2.22.2 (ASCIILiteral, sanitizeStackForVM, vm.heap.collectNow, etc.). Non-critical for CVE fix.

🔍 CVE 项目匹配性分析结果
CVE: CVE-2026-78376
针对分支: master
结果: ❌ 不匹配
原因: CVE 存在：NVD totalResults=1（secalert@redhat.com，2026-08-24 发布，CVSS 8.8），MITRE 记录状态 PUBLISHED，标题 use-after-free of jscvalue function parameters，与 Issue body 描述一致；Issue 参考链接（NVD/Red Hat Bugzilla 2521858/Red Hat CVE/WebKit PR 72142/Debian tracker）均指向同一漏洞，无 GHSA 链接。组件匹配：受影响产品 WebKitGTK/webkitgtk，与项目包名 webkitgtk 一致。版本匹配：MITRE 标记 WebKitGTK >=2.21.1 均受影响，Issue 受影响版本列表含 2.52.1/2.52.3（与当前 2.52.6 同一次版本系列），且 Issue 自身排查标记 master(2.52.6) 为受影响，当前版本处于受影响范围。备注：master 分支 webkitgtk.spec（2.52.6-2）已含 Patch6000 backport-CVE-2026-78376.patch（changelog: fix CVE-2026-78376，2026-09-01，为上游 9fa946d9a72f / 319867@main 的 cherry-pick），后续方案设计阶段须先做存量检查（already_fixed），避免重复提交补丁。
建议:
- 此 CVE 实际影响的项目与当前 Issue 所在项目不一致
- 建议关闭此 Issue，或将其移至正确项目的 Issue 列表
- 如有疑问，请联系安全团队确认
