Google Chrome Passwords: Memory corruption allows code execution in sandbox
Summary
Google Chrome desktop versions before 156.0.8078.47 contain a memory corruption flaw in the Passwords component (CWE-119). A remote attacker can execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. The description does not state a sandbox escape, so full system compromise is not described by this CVE.
Affected
- Google Chrome desktop builds prior to 156.0.8078.47
- Chromium-based products that include the same Passwords code are not covered by this record; check their vendors' advisories
Fixed in
- Google Chrome 156.0.8078.47 or later (Linux)
- Google Chrome 156.0.8078.47 or later (Windows and macOS, per secondary reports)
- Verify exact build numbers against the Chrome Releases advisory, which was not directly accessible during research
Workaround
- No workaround is known. Apply the Chrome update.
- Fully restart Chrome after updating, because an old browser process may still run after the update.
Exploitation
- Exploited in the wild: Unknown. No exploitation reports were found.
- Public proof of concept: None found.
- Google rates the issue Low (Chromium security severity). NVD base score: 8.8 (CVSS 3.1, AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
- CISA SSVC: Exploitation none, Automatable no, Technical impact total.
Our recommendation
- Update Google Chrome to 156.0.8078.47 or later on all endpoints, including managed devices, and restart the browser.
- Check the installed Chrome version centrally, for example through the endpoint management tool.
- Monitor for updates and treat this release as part of the wider Chrome 156 security update, which contains many fixes.
- Check the Chromium-based browsers and Linux packages used in your environment against their own vendor advisories.
