Google Chrome: Use-after-free in V8 JavaScript engine allows sandboxed code execution
Summary
A use-after-free flaw in the V8 JavaScript engine of Google Chrome (CWE-416) lets a remote attacker execute arbitrary code inside the browser sandbox. The attacker needs the victim to open a crafted HTML page, so any web browsing or web-based mail can expose the flaw. The sources describe code execution in the renderer sandbox only; a separate sandbox escape would be needed for full system compromise, and none is described.
Affected
- Google Chrome prior to 155.0.8059.79 (desktop, per the CVE description)
- Older affected branches: Unknown.
- Other Chromium-based browsers (e.g. Edge, Brave, Vivaldi): Unknown, check with the vendor.
Fixed in
- Google Chrome 155.0.8059.79 or later (Chrome Releases, 13 Oct 2026)
- Linux distributions: use the distribution's advisory for exact package versions (e.g. Debian tracker lists 155.0.8059.79-1~deb12u1 for bookworm)
Workaround
- No workaround documented in the sources. Update is the only remediation found.
- Restart the browser after updating, because a long-running session keeps the old code loaded.
Exploitation
- CISA SSVC assessment: exploitation none, not automatable, total technical impact.
- Not listed in the CISA KEV catalogue according to a secondary aggregator (unverified).
- No public proof of concept known.
- No in-the-wild exploitation reported in the sources found.
Our recommendation
- Update Google Chrome to 155.0.8059.79 or later on all endpoints and verify the running version.
- Restart Chrome after the update.
- Patch the whole Chrome 155 release, which also fixed 37 further security issues.
- Check Chromium-based browsers and Linux packages separately, as they may have their own fixed builds.
- Monitor for unusual browser crashes or behaviour.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
