Google Chrome: Use after free in Navigation allows sandboxed code execution
Summary
Google Chrome prior to 156.0.8078.47 contains a use-after-free flaw in the Navigation component (CWE-416). A remote attacker can execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. The attack requires that the user opens the page, and the CVSS base score is 8.8 (High).
Affected
- Google Chrome prior to 156.0.8078.47 (desktop)
- Chromium-based browsers that have not yet taken the fix are also affected (Unknown which exact builds)
Fixed in
- Google Chrome 156.0.8078.47 (Linux), 156.0.8078.48 (Windows and macOS) or later
- Newer stable builds are available; install the newest stable version
- Debian issued DSA-6577-1 and DLA-4853-1 for Chromium
- Ubuntu chromium-browser package: not affected (uses Chromium snap, check snap channel)
- Microsoft Edge: fixed via Chromium; exact Edge build numbers unverified
Workaround
- Unknown. No vendor workaround identified; apply the update.
Exploitation
- No evidence of exploitation in the wild found (CISA KEV not verified directly).
- No public proof of concept found in limited searches.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
Our recommendation
- Update Google Chrome to the newest stable build on all endpoints, including Chromium-based Edge and other Chromium-derived browsers.
- Enforce update policies through management tools and verify that the update is applied, not just downloaded; relaunch the browser.
- Check for machines that cannot be updated and treat them as an open risk.
- Monitor for exploitation reports and re-check the vendor advisory before closing the ticket.
