Google Chrome: Use after free in Input component allows sandboxed code execution
Summary
Google Chrome before 156.0.8078.47 contains a use-after-free flaw in the Input component (CWE-416). A remote attacker can use a crafted HTML page to potentially execute arbitrary code inside the browser sandbox. The attack requires that a user visits the malicious page, and no authentication is needed.
Affected
- Google Chrome prior to 156.0.8078.47
- Microsoft Edge prior to 156.0.4314.42 (Chromium-based, third-party report)
- Linux distributions shipping Chromium: check their advisories (for example Debian DSA 6577-1, DLA 4853-1); Ubuntu lists chromium-browser as not affected, but the snap package must be checked separately
Fixed in
- Google Chrome 156.0.8078.47 or later (Windows and Mac builds reported as 156.0.8078.47 or 156.0.8078.48; latest stable builds 156.0.8078.79 or later)
- Microsoft Edge 156.0.4314.42 or later
- Linux distributions: according to their respective security advisories
Workaround
- Unknown. No vendor workaround is known.
- Enforce automatic Chrome updates and a minimum version through endpoint management.
Exploitation
- No evidence of exploitation in the wild found at the time of research.
- No public proof of concept found.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
Our recommendation
- Update all Chrome and Edge installations to the latest stable version and restart the browsers afterwards.
- Check Linux systems against their distribution advisories.
- Prioritise administrator workstations and users who browse untrusted websites.
- Recheck the Chromium tracker, NVD and CISA KEV in a few days for changes in exploitation status.
