Google Chrome: Use-after-free in Google Lens allows sandbox code execution
Summary
Google Chrome versions before 156.0.8078.47 contain a use-after-free flaw in the Google Lens component. A remote attacker can use a crafted HTML page to execute arbitrary code inside the browser sandbox. No login is required, but the victim must load the malicious page, for example through a link in an email or while browsing.
Affected
- Google Chrome prior to 156.0.8078.47 (desktop: Windows, macOS, Linux)
- Chromium-based browsers and Linux distributions depend on their own fixes and were not verified in this entry
Fixed in
- Google Chrome 156.0.8078.47 or later; the current stable build is recommended
- Newer October 2026 Chrome builds also include this fix
Workaround
Unknown.
Exploitation
- No evidence found of in-the-wild exploitation or public proof of concept
- Not listed in CISA KEV in the sources reviewed, but the KEV catalogue was not directly checked
Our recommendation
- Update Chrome on all managed systems to 156.0.8078.47 or later, preferably the current stable build, and prioritise this update
- Check Chromium-based browsers (e.g. Edge) and Linux packages separately, as they ship their own fixes
- Verify the installed version under Menu > Help > About Google Chrome
- Monitor for changes in exploitation status
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
