Google Chrome: Use after free in Loader allows code execution in sandbox
Summary
A use-after-free vulnerability (CWE-416) in the Loader component of Google Chrome allows a remote attacker to execute arbitrary code inside the browser sandbox. Exploitation requires the victim to visit a crafted HTML page, for example via phishing or a compromised website. The CVE description does not state a sandbox escape, and Chromium rates the issue Low severity.
Affected
- Google Chrome prior to 156.0.8078.47 (per CVE description)
- Chromium-based products that consume the affected code are not confirmed; Ubuntu lists its chromium-browser snap as not affected
- Microsoft Edge: fixed version listed as 156.0.4314.42 or later (not verified against Microsoft)
Fixed in
- Google Chrome 156.0.8078.47 or later (latest stable build recommended; newer builds exist)
- Microsoft Edge 156.0.4314.42 or later (unverified)
- Debian chromium updates DSA 6577-1 and DLA 4853-1 (contents not verified)
Workaround
- No workaround needed where a patch is available
- Where updates are blocked, restrict browsing to trusted sites or use managed browser policies; no vendor-specific workaround is known
Exploitation
- No evidence of exploitation in the wild found; not verified against CISA KEV
- No public proof of concept found
- EPSS 0.00417 for the related Chromium entry (low estimated probability)
Our recommendation
- Update Google Chrome and Chromium-based browsers, including Microsoft Edge, to the latest stable version through normal update channels
- Verify installed browser versions across the fleet, including unmanaged installations
- Check that automatic browser updates are not disabled by policy and that browsers are relaunched after updates
- Monitor for exploitation indicators and review the vendor advisory once accessible
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
