- Google fixes high severity bug in Chrome V8 (CVE‑2026‑11645) exploited in the wild
- Flaw allows remote code execution via HTML crafted in versions prior to 149.0.7827.103
- The fixes are now available for Windows, Mac and Linux; Users are urged to update immediately.
Google has fixed a high-severity vulnerability in its Chrome browser that was apparently being abused.
The company has published a new security advisory informing users how to fix dozens of flaws, including an out-of-bounds read/write bug in Chrome V8 that could allow remote attackers to execute arbitrary code within a sandbox via a crafted HTML page, which was found in Google Chrome before 149.0.7827.103.
The issue is now tracked as CVE-2026-11645 and has been assigned a severity score of 8.8/10 (High).
No details about the attacks.
In theory, the flaw could be used to steal corporate emails, documents, session cookies or other sensitive information. All it takes is for a person to open a crafted page on a vulnerable version of Chrome to trigger the exploit.
“Google is aware that an exploit exists for CVE-2026-11645,” Google said in the advisory, without sharing any details. “Access to the bug details and links may remain restricted until the majority of users are updated with a fix,” the company added. “We will also maintain restrictions if the bug exists in a third-party library that other projects similarly depend on but have not yet fixed.”
The bug has now been fixed in the stable desktop channel with patches released for Windows (149.0.7827.102), Mac (149.0.7827.103), and Linux (149.0.7827.102).
Google often says that the patch takes weeks to roll out globally, but in most cases, by the time the notice is published, most browsers will have already been patched. Those who are unsure if their Chrome is up to date should navigate to chrome://settings/help in the address bar, press Enter, and wait while Chrome checks for updates. If any are found, you will be prompted to download and install them.
