Google Chrome: Use after free in Network component allows code execution
Summary
A use-after-free flaw in the Network component of Google Chrome before 155.0.8059.79 can be triggered by crafted network traffic. According to the CVE record, a remote attacker can execute arbitrary code outside the browser sandbox. The attack requires that a user visits a page or loads content, but no login.
Affected
- Google Chrome for Windows, Mac and Linux prior to 155.0.8059.79
- Chromium packages of Linux distributions that are not yet updated (e.g. Debian chromium before 155.0.8059.79-1~deb12u1)
- Chrome for Android: unconfirmed, sources disagree
- Ubuntu chromium-browser (snap wrapper): marked as not affected by Ubuntu
Fixed in
- Windows and Mac: 155.0.8059.79 or later
- Linux: 155.0.8059.79 or later
- Debian chromium: 155.0.8059.79-1~deb12u1
- Android: unconfirmed, check against the Google advisory
Workaround
Unknown. No workaround is documented. Install the browser update and restart Chrome, because running processes can keep using the old version.
Exploitation
- Google's post reports no attacks in the wild (not verified against the primary advisory)
- Not listed in the CISA KEV catalog at the time of research
- No public proof of concept found
- EPSS scores from third parties are low
Our recommendation
- Treat as high priority for managed fleets.
- Inventory the Chrome version on all Windows, Mac and Linux devices and flag anything below 155.0.8059.79.
- Check Android devices against the Google advisory.
- Restart Chrome after the update.
- Confirm that Chromium-based browsers such as Edge have their own updates installed.
- Monitor the CISA KEV catalog for changes.

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