Google Chrome: Use after free in GPU component allows sandbox code execution
Summary
Google Chrome versions before 156.0.8078.47 contain a use-after-free flaw in the GPU component. A remote attacker can execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. The attack requires user interaction, such as visiting the page.
Affected
- Google Chrome prior to 156.0.8078.47 (desktop)
Fixed in
- Google Chrome 156.0.8078.47 or later
Workaround
- Unknown. No workaround is documented; updating Chrome is the remedy.
Exploitation
- CISA SSVC: exploitation none, not automatable, total technical impact.
- No public exploitation is documented in the sources reviewed.
Our recommendation
- Update Google Chrome to 156.0.8078.47 or later on all desktop systems.
- Check that Chromium-based browsers (for example Microsoft Edge) and Chromium packages are updated through their own vendors.
- Restart the browser after the update so the new version takes effect.
- Prefer automatic updates and monitor the vendor advisory for further builds.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
