Google Chrome: Use-after-free in Compositing component
Summary
Google Chrome for desktop contains a use-after-free flaw (CWE-416) in the Compositing component, which handles drawing of page content. A remote attacker can host or inject a crafted HTML page; when a user visits it, the attacker may execute arbitrary code inside the browser sandbox. The attack requires user interaction (opening the page) but no privileges.
Affected
- Google Chrome for Windows, macOS and Linux prior to 155.0.8059.84
Fixed in
- Google Chrome 155.0.8059.84 (Windows and macOS: 155.0.8059.84/.85; Linux: 155.0.8059.84)
- Later stable releases also include the fix; install the latest stable version
Workaround
- No workaround is known. Update Chrome.
- Keep automatic updates enabled or enforce a minimum Chrome version via management tools or group policy.
Exploitation
- Google has not reported active exploitation in the wild.
- CISA SSVC assessment: exploitation none, not automatable, total technical impact.
- Not listed in the CISA KEV catalog.
- No public proof of concept known.
Our recommendation
- Update Google Chrome on all endpoints to the latest stable version.
- Verify the Chrome version on managed devices and enforce a minimum version.
- Restrict or monitor browsing of untrusted sites on systems that have not been updated.
- Check whether other Chromium-based browsers (e.g. Edge, Brave) are installed and update them per their vendors' advisories.

PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
