Google Chrome: Use-after-free in GPU allows code execution in sandbox
Summary
A use-after-free vulnerability in the GPU component of Google Chrome allows a remote attacker to execute arbitrary code inside the browser sandbox. The attacker needs to lure a user to a crafted HTML page; no login is required. The sources do not describe a sandbox escape, so impact beyond the sandbox is unknown. Chromium rates the issue High, and the CVSS 3.1 base score is 8.8.
Affected
- Google Chrome prior to 156.0.8078.47 (according to the CVE description)
- The official CVE record lists the range as 156.0.8078.47 to < 156.0.8078.47, which conflicts with the description; verify on NVD
- Microsoft Edge: according to a HKCERT bulletin, versions before 156.0.4314.42 (unverified; check MSRC)
Fixed in
- Google Chrome 156.0.8078.47 or later
- Later Chrome 156 stable builds (secondary sources report 156.0.8078.79/.80) also contain the fix
- Microsoft Edge 156.0.4314.42 or later (HKCERT, unverified)
Workaround
Unknown. No vendor workaround identified; apply the update.
Exploitation
- No known exploitation in the wild in the sources reviewed
- No public proof of concept found
- CISA KEV status not verified
- EPSS 0.00443 (Red Hat listing), a low predicted exploitation probability
Our recommendation
- Update Google Chrome and Chromium-based Edge to the latest stable build and verify the installed version on all endpoints
- Restart the browser after updating, because Chrome applies updates on relaunch
- Keep automatic browser updates enabled
- Check the CISA KEV catalogue and the vendor advisory for changes
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
