Google Chrome: Use-after-free in Blink rendering engine
Summary
A use-after-free flaw in the Blink rendering engine of Google Chrome before 156.0.8078.79 allows a remote attacker to execute arbitrary code inside the browser sandbox. The attacker needs the victim to open a crafted HTML page (user interaction required) and no prior privileges. Exploitation of the sandbox alone does not give full system control, and the sources describe no sandbox escape.
Affected
- Google Chrome desktop versions prior to 156.0.8078.79
Fixed in
- Google Chrome 156.0.8078.79 or later (Chrome Stable Channel update of 29 October 2026)
Workaround
- No vendor workaround documented. Apply the update.
- Until patched, avoid browsing untrusted sites and do not open unknown links in Chrome.
Exploitation
- No exploitation in the wild reported in the sources reviewed.
- Not listed in CISA KEV according to third-party trackers; the live KEV catalogue was not checked directly.
- No public proof-of-concept found as of 29 October 2026.
Our recommendation
- Check all managed Chrome installations for version 156.0.8078.79 or later on Windows, macOS and Linux.
- Restart Chrome so the update takes effect.
- Confirm auto-update is enabled on all devices.
- Re-check CISA KEV and public exploit listings within a few days.
