CVE-2026-85046-who-put-the-silverback-guerilla-in-the-wasm

CVE-2026-85046 この脆弱性の他のPOCを見て、これは見るのが本当に悪夢だと思いました。そこでPOCを簡素化し、独自のwasmへのジャンプを追加しました。なぜならwasmだからです。 Chrome 152.0.7977.75は、sort実行中にオブジェクトポインタと整数を混同する可能性があります。 poc.jsは古いWasmモジュール参照を保持し、解放されたセルを別のモジュールで置き換えた後、その古い参照を通じて置換モジュールを呼び出します。 sortはWasmモジュールポインタを整数としてリークします。 ポインタはGCが追跡しない場所に保存されます。...
