Google Chrome: Memory corruption in DevTools
Summary
Memory corruption in the DevTools component of Google Chrome before 156.0.8078.47 can be exploited by a remote attacker. A crafted HTML page can potentially execute arbitrary code inside the browser sandbox. The attack requires the user to visit the malicious page, and no exploitation has been reported.
Affected
- Google Chrome desktop before 156.0.8078.47
Fixed in
- Google Chrome 156.0.8078.47 or later. Newer Chrome 156 builds are also available.
Workaround
Unknown. Keep Chrome auto-update enabled and not blocked by policy.
Exploitation
- No evidence of exploitation in the wild was found. The CISA KEV status shown by one aggregator is 'No', which was not checked directly.
- No public proof of concept was found. Chromium rates the severity as Low.
Our recommendation
- Confirm that all Chrome, Edge and other Chromium-based browsers run at least 156.0.8078.47, preferably the latest 156 build.
- Check that auto-updates work and are not blocked by policy.
- Monitor the CISA KEV catalog and the Chromium bug page for changes.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
