Google Chrome: Use after free in DOM allows code execution in sandbox
Summary
Google Chrome prior to 155.0.8059.79 contains a use-after-free flaw in the DOM component. A remote attacker can potentially execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. The attack requires the victim to visit the malicious page, and the CVSS score is 8.8 (High).
Affected
- Google Chrome prior to 155.0.8059.79 (Windows, macOS and Linux)
- Chromium-based browsers that have not yet ingested the upstream fix are also potentially affected
Fixed in
- Google Chrome 155.0.8059.79 (Linux) and 155.0.8059.79/.80 (Windows and macOS)
- Install the newest Stable build, as later builds may also contain the fix
- Debian: 155.0.8059.79-1~deb12u1 for bookworm (DSA 6562-1, DLA 4838-1)
- Ubuntu: chromium-browser packages are not affected because they install the Chromium snap
Workaround
- Unknown: no interim mitigation published by Google was found
- Update the browser; no other workaround is available
Exploitation
- No evidence of exploitation in the wild, according to CISA ICS-CERT
- Not listed in CISA KEV as of the latest data found
- No public proof of concept found
- Low EPSS score (about 0.2%) reported by third-party trackers
Our recommendation
- Update Google Chrome to 155.0.8059.79 or later, preferably the newest Stable build
- Check that all managed devices are updated, including Microsoft Edge and other Chromium-based browsers
- Restart the browser after the update, as restarts are often delayed
- Use Chrome Enterprise update channel management to enforce timely updates
- Remind users not to open links from unknown sources and to be cautious with phishing emails
