Google Chrome: Memory corruption in WebProtect component
Summary
A memory corruption flaw in the WebProtect component of Google Chrome before 156.0.8078.47 can be triggered by a crafted HTML page. An attacker could potentially execute arbitrary code inside the browser sandbox. Exploitation requires that a user visits the malicious page. Google rates the issue as Low severity, and the CVSS score of 8.8 could not be verified against NVD.
Affected
- Google Chrome prior to 156.0.8078.47 (desktop)
- Chromium-based browsers, such as Microsoft Edge, may be affected until they ship the Chromium fix
Fixed in
- Google Chrome 156.0.8078.47 or later. Deploy the latest Stable or Extended Stable build, as newer 156.0.8078.x releases exist.
- Microsoft Edge: check the Microsoft advisory for the fixed build.
- Linux distributions: check the vendor advisories for fixed Chromium package versions.
Workaround
- Unknown. No workaround found; updating the browser is the remedy.
Exploitation
- No known exploitation in the wild and no public proof of concept found at the time of writing.
- Google rates the severity as Low (Chromium security severity: Low).
- CISA SSVC: exploitation none, automatable no, technical impact total.
Our recommendation
- Update Chrome and other Chromium-based browsers to the latest stable version on all workstations.
- Verify the installed version via browser settings or endpoint management.
- Treat this as priority routine patching, because browsers are internet-facing.
- Monitor for unusual browser crashes and restrict browsing to trusted sites where possible.
