Vulnerabilities & ExploitsGoogle Patches Actively Exploited V8 Zero-Day in Chrome (CVE-2026-85046)
Google has released an urgent update for Chrome to address CVE-2026-85046, a high-severity zero-day vulnerability in the V8 JavaScript and WebAssembly engine that is being actively exploited in the wild. The flaw is a type confusion issue tied to the Maglev compiler and optimizations around Array.prototype.sort, which can lead to arbitrary memory read and write primitives inside the JavaScript heap. Successful exploitation allows a remote attacker to execute arbitrary code within the browser sandbox after a victim visits a specially crafted HTML page, a technique commonly seen in malvertising and compromised-site campaigns. The fix is included in Chrome 152.0.7977.82 and later for Windows, macOS, and Linux, and the update also resolves a total of twelve vulnerabilities. The vulnerability was reported on 4 August 2026 by researcher Salvatore Gulizia, known as Serotav, who received a $1,000 reward. Other Chromium-based browsers such as Microsoft Edge, Brave, Opera, and Vivaldi will require corresponding updates from their respective vendors.
Google Chrome Patches 12 Vulnerabilities Including Actively Exploited V8 Zero-Day
Google has released security updates for Chrome addressing 12 vulnerabilities across Windows, macOS, and Linux platforms. The updates include versions 152.0.7977.83 and 152.0.7977.82 for Windows and macOS, and 152.0.7977.82 for Linux. No critical-rated flaws were fixed in this batch, but ten issues carry a high severity rating. The most notable is CVE-2026-85046, a type confusion flaw in the V8 JavaScript engine that was reported on August 4 and is already being exploited in the wild. Additional high-severity fixes cover a race condition in V8 (CVE-2026-85045), a use-after-free in Compositing (CVE-2026-85048), and another type confusion issue (CVE-2026-85051). This marks the second Chrome security update in three days.
