Google Chrome: Use-after-free in Internals allows code execution outside sandbox
Summary
A use-after-free vulnerability in the Internals component of Google Chrome before 156.0.8078.47 allows a remote attacker to execute arbitrary code outside the Chrome sandbox. The attacker only needs to lure a user to a crafted HTML page, and no login is required. NVD rates it 9.6 (critical), while Google rates it Medium; plan for the higher score on internet-facing endpoints.
Affected
- Google Chrome desktop prior to 156.0.8078.47 (Windows, Mac, Linux)
Fixed in
- Google Chrome 156.0.8078.47 according to the CVE description
- Whether later builds (156.0.8078.73 and up) include this fix is unconfirmed
Workaround
- Unknown. No workaround found in any source; apply the update and restart the browser.
Exploitation
- Not reported as exploited in the wild by Google.
- Public proof of concept: none found.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
- EPSS score: unknown.
Our recommendation
- Update Google Chrome on all managed desktops to the latest stable build, at least 156.0.8078.47.
- Restart browsers after the update, since a staged update is not active until restart.
- Confirm the installed version through device inventory, including shared and kiosk systems.
- Check Chromium-based browsers (for example Microsoft Edge) for their own updates.

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