Google Chrome: Use-after-free in DOM allows sandboxed code execution
Summary
Google Chrome versions before 155.0.8059.79 contain a use-after-free vulnerability in the DOM component. A remote attacker can execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. Exploitation requires that the user visits the page, and a full compromise typically needs an additional sandbox escape that is not described.
Affected
- Google Chrome before 155.0.8059.79 (desktop)
- Debian: chromium before 155.0.8059.79-1~deb12u1
- Ubuntu: Chromium snap (chromium-browser deb package is not affected)
Fixed in
- Google Chrome 155.0.8059.79 or later (Windows, Linux); 155.0.8059.79/.80 (Windows, Mac), per Stable Channel Update for Desktop of 13 October 2026
- Debian: 155.0.8059.79-1~deb12u1 (DSA 6562-1)
- Fedora 43 and 44: chromium update issued
Workaround
- No workaround needed; apply the vendor update.
- Ensure Chrome auto-update works and restart the browser to complete a pending update.
- Use Chrome enterprise release channels to control the rollout.
Exploitation
- Not known to be exploited in the wild; not listed in CISA KEV.
- EPSS is low (0.22% per a GitHub aggregator).
- No public proof-of-concept found.
- CISA SSVC: exploitation none, automatable no, technical impact total.
Our recommendation
- Confirm all Chrome installations (Windows, Mac, Linux, Android) run 155.0.8059.79 or later, or the distribution versions listed above.
- Check EDR or MDM reports for Chrome builds older than 155.0.8059.79.
- Restart browsers that have a pending update.
- Re-check CISA KEV and the Chrome release page for changes.
