Google Chrome: Use after free in Navigation allows sandboxed code execution
Summary
Google Chrome before 156.0.8078.47 contains a use-after-free vulnerability in the Navigation component (CWE-416), rated High by Chromium. 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 full system compromise would normally need a second sandbox-escape flaw.
Affected
- Google Chrome versions before 156.0.8078.47
- VulDB lists the affected range up to 155.0.8059.84
- Chromium-based browsers that ingest the same Chromium fix may be affected until they ship their own update
Fixed in
- Google Chrome 156.0.8078.47 for Linux
- Windows and Mac: sources differ between 156.0.8078.47 and 156.0.8078.48; confirm against the vendor advisory
- Newer Stable builds (156.0.8078.79/.80 cited in secondary sources) are available and should be preferred
Workaround
No workaround needed, a patch is available. Restart the browser after the update, because Chrome applies updates on relaunch.
Exploitation
- In the wild: no evidence found; no CISA KEV entry or vendor 'exploited' flag found
- Public proof of concept: none found
- EPSS: 0.00443 (low predicted exploitation probability)
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total
Our recommendation
- Update Google Chrome to the latest Stable build on all workstations and restart the browser
- Verify build numbers on endpoints, including Chromium-based browsers such as Microsoft Edge, and enforce a minimum version via patch tooling
- On Linux, check whether Chrome comes from Google's repository or a distribution package
- Prioritise internet-facing user workstations within the standard browser patch cycle
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
