Google Chrome: Use-after-free in Privacy component
Summary
Google Chrome versions before 156.0.8078.47 contain a use-after-free flaw in the Privacy component (CWE-416, NVD CVSS 8.8). A remote attacker can run arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. The CVE record does not describe a sandbox escape, so full compromise would need a further step. Chromium-based browsers such as Microsoft Edge are affected as well.
Affected
- Google Chrome prior to 156.0.8078.47 (per CVE record)
- Microsoft Edge prior to 156.0.4314.42 (per HKCERT; confirm with MSRC)
- Other Chromium-based browsers: check the vendor advisories
Fixed in
- Google Chrome 156.0.8078.47 or later (Linux)
- Google Chrome 156.0.8078.48 or later (Windows and macOS, per Wikipedia; confirm with Google's notice)
- Microsoft Edge 156.0.4314.42 or later
- Debian and Ubuntu package versions: not verified.
Workaround
Unknown. No vendor workaround found; apply the update and restart the browser.
Exploitation
- No evidence of exploitation in the wild found; not listed in CISA KEV at time of research.
- No public proof of concept found.
- CISA SSVC: exploitation none, not automatable.
- EPSS 0.00443 (low).
Our recommendation
- Inventory Chrome and Chromium-based browsers on all endpoints.
- Update Chrome to 156.0.8078.47 or later (156.0.8078.48 on Windows and macOS) and Edge to 156.0.4314.42 or later.
- Restart browsers and verify the running version.
- Enforce automatic updates via group policy or MDM.
- Patch within days, because attacks can be delivered through crafted web pages.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
