Google Chrome: Use-after-free in SVG component allows code execution
Summary
Google Chrome contains a use-after-free vulnerability (CWE-416) in its SVG component. A remote attacker can use a crafted HTML page to execute arbitrary code inside the browser sandbox. The attack requires that a user visits the malicious page, and no authentication is needed. NVD rates the issue 8.8 (High), while Chromium rates it Critical.
Affected

Workaround
Unknown. No vendor-documented workaround found. Apply the update.
Exploitation
- No evidence of in-the-wild exploitation found.
- No public proof-of-concept code found in the searches performed.
- CISA SSVC assessment: Exploitation none, Automatable no.
- Whether a sandbox escape chain exists is unknown.
Our recommendation
- Update Google Chrome to the latest stable version, at least 155.0.8059.79.
- Verify that automatic updates are not blocked on managed devices.
- Check other Chromium-based browsers and Linux packages against their own advisories.
- Monitor for public proof-of-concept code or changes in exploitation status.
