Google has shipped an emergency Chrome fix for a zero-day in V8, the browser's JavaScript and WebAssembly engine, that attackers are already exploiting in the wild. The flaw (CVE-2026-11645, rated 8.8) is an out-of-bounds memory read and write that lets a malicious web page run code inside Chrome's sandbox, and can help defeat protections like ASLR to set up a fuller compromise. Google confirmed an exploit exists but withheld details until most users update. It is the fifth actively exploited Chrome zero-day of 2026. The fix is in Chrome 149.0.7827.102/103 for desktop; Chromium-based browsers like Edge and Brave need the same update.
Google shipped Chrome 149 with fixes for 429 security bugs, the most ever in a single Chrome release. More than 100 are rated critical or high. The worst, an out-of-bounds read and write in the ANGLE graphics engine that Chrome uses to render web pages, lets a booby-trapped website break out of the browser's protective sandbox and run code on the victim's computer; Google paid a $97,000 bounty for it. None are confirmed under attack yet, but a sandbox escape is the kind of bug attackers race to weaponize, so patching before that happens matters.
Google overhauled its Vulnerability Reward Program for Android and Chrome on May 1 in response to AI tools reshaping bug hunting. The maximum Pixel Titan M reward jumped to $1.5 million for a zero-click exploit with persistence. Chrome payouts dropped across categories. Google is rewarding 'actionable reports' with concrete exploits and suggested fixes rather than raw bug volume - a response to AI tools like Anthropic's Mythos and OpenAI's GPT-5.4-Cyber generating more vulnerability reports than security teams can triage. Google paid a record $17.1 million in 2025 (up 40% from 2024) and expects 2026 aggregate rewards to increase further despite per-bug cuts.
Google pushed an emergency Chrome update to fix a use-after-free bug in Dawn, the engine behind Chrome's WebGPU graphics standard. CVE-2026-5281 is already being exploited - an attacker who has compromised the browser's renderer process can use a crafted HTML page to execute arbitrary code, potentially escaping Chrome's sandbox. This is the fourth actively exploited Chrome zero-day in 2026, and the third targeting graphics or rendering subsystems. CISA added it to the KEV catalog with an April 15 deadline.
