Google Chrome: Use-after-free in Navigation allows code execution
Summary
A use-after-free flaw in the Navigation component of Google Chrome allows a remote attacker to execute arbitrary code outside the browser sandbox. The attacker needs the victim to open a crafted HTML page, so no privileges or prior access are required. The CVSS 3.1 score is 9.6 (Critical), with high impact on confidentiality, integrity and availability.
Affected
- Google Chrome desktop versions prior to 155.0.8059.39 (per the CVE description)
- Chromium-based browsers and packages that include the affected Chromium code may be affected until they ship the fix
Fixed in
- Google Chrome 155.0.8059.39 for Windows and Linux, 155.0.8059.40 for Mac (Stable channel update of 6 October 2026)
- Later Stable builds also include the fix; use the latest Stable build
- Chromium-based browsers and Linux distribution packages: fix availability depends on the vendor
Workaround
Unknown. No vendor workaround is published. Updating and restarting the browser is the practical mitigation.
Exploitation
- Not known to be exploited in the wild
- Not listed in the CISA Known Exploited Vulnerabilities catalogue
- CISA SSVC data: exploitation none, automatable no
- No public proof-of-concept found
Our recommendation
- Check every Chrome installation and make sure it runs 155.0.8059.39 or later (Mac: 155.0.8059.40 or later), or the latest Stable build
- Restart the browser on machines with pending updates and enforce update policies through your management tool
- Inventory Chromium-based apps and embedded runtimes separately and update them
- Monitor the CISA KEV catalogue and Google's Stable channel updates for changes
