Google Chrome: Memory corruption in Model allows code execution in sandbox
Summary
A memory corruption flaw in the Model component of Google Chrome before 156.0.8078.47 allows a remote attacker to execute arbitrary code inside the browser sandbox. The attack requires a user to open a crafted HTML page; no authentication is needed. Chromium rates the issue Low, and the sources describe impact only within the sandbox, with no sandbox escape documented.
Affected
- Google Chrome prior to 156.0.8078.47 (per CVE description)
- Microsoft Edge and other Chromium-based browsers may be affected (HKCERT lists Edge fixed at 156.0.4314.42)
Fixed in
- Google Chrome 156.0.8078.47 (Windows and macOS builds may show 156.0.8078.48)
- Microsoft Edge 156.0.4314.42 (per HKCERT)
- Linux distributions: check the vendor status for your distribution (Ubuntu lists its Chromium snap as not affected)
Workaround
- No workaround known. Applying the update is the mitigation.
- No vendor-documented interim mitigation.
Exploitation
- Exploited in the wild: Unknown.
- Public proof of concept: none found.
- CISA SSVC: Exploitation none, Automatable no, Technical impact total.
Our recommendation
- Confirm that all managed Chrome and Edge endpoints run 156.0.8078.47 or later (Edge 156.0.4314.42 or later).
- Verify that automatic browser updates work and restart browsers to apply pending updates.
- Prioritise this update, as the same release contains other Chromium security fixes.
