Google Chrome: Use-after-free in Input allows code execution in sandbox
Summary
A use-after-free vulnerability in the Input component of Google Chrome desktop allows a remote attacker to execute arbitrary code inside the browser sandbox. Exploitation requires the victim to open a crafted HTML page, so the risk is drive-by via malicious or compromised websites. Full compromise typically requires an additional sandbox escape, which is not described in this CVE.
Affected
- Google Chrome desktop versions prior to 156.0.8078.47
- Chromium-based browsers that ingest the same fix, such as Microsoft Edge (exact affected build to be confirmed in the MSRC entry)
Fixed in
- Google Chrome 156.0.8078.47 or later (the vendor advisory should be checked for the exact build per platform, as sources differ between .47 and .48)
- Microsoft Edge: fixed version per MSRC (a third-party bulletin cites 156.0.4314.42 or later)
- Ubuntu: fix delivered via the Chromium snap (chromium-browser package marked Not affected)
Workaround
- No vendor workaround identified. Updating is the remedy.
Exploitation
- CISA SSVC assessment: Exploitation none, Automatable no, Technical Impact total.
- No evidence of in-the-wild exploitation or public proof-of-concept code was found. This means no information was found, not that exploitation is ruled out.
- A similar CVE-2026-76031 (fixed in 156.0.8078.79) is not to be confused with this CVE.
Our recommendation
- Verify that all Chrome endpoints run 156.0.8078.47 or later and that Edge runs the MSRC-fixed version.
- Enforce browser restart after updates, as machines that are rarely restarted may remain unpatched.
- Check managed fleets and Linux systems using the Chromium snap.
- Patch deployment priority: high. Not an emergency unless exploitation is reported.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
