Google warns of new Chrome zero-day flaw exploited in attacks

Google has updated the Chrome browser to address an actively exploited high-severity zero-day flaw in the V8 engine and 11 other vulnerabilities. The exploited security issue, identified as CVE-2026-85046, is described as a type confusion. It was reported to Google by researcher Salvatore Gulizia, known online as “Serotav.” The update brings Chrome to version 152.0.7977.82/.83 on Windows and macOS, and 152.0.7977.82 on Linux, as part of a gradual rollout.. “Google is aware that an exploit for CVE-2026-85046 exists in the wild,” the advisory reads. The company did not disclose any technical or specific exploitation details about the flaw to give users and dependent projects time to apply the fix. Type confusion flaws cause software to misinterpret one type of object as another, allowing attackers to corrupt memory. V8 is Chrome’s open-source JavaScript and WebAssembly engine, which compiles and executes code used by websites. Hence, CVE-2026-85046 could potentially be triggered by a specially crafted HTML page containing malicious JavaScript, potentially allowing remote code execution within Chrome's sandboxed renderer process. The update also addresses nine other high-severity vulnerabilities, including use-after-free and out-of-bounds memory flaws in Crash Reporting, Network, Compositing, WebGL, CacheStorage, DevTools, Skia, and a race condition in V8. CVE-2026-85046 is the sixth actively exploited bug Google has fixed in Chrome since the start of the year. Previous fixes i...
