Google Chrome: Memory corruption in DevTools allows sandboxed code execution
Summary
Google Chrome desktop versions before 156.0.8078.47 contain a memory corruption flaw in the DevTools component. A remote attacker can create a crafted HTML page that may lead to arbitrary code execution inside the browser sandbox. The attack requires a user to visit the malicious page, and Chromium rates the severity as Low because the impact is limited to the sandbox.
Affected
- Google Chrome desktop versions before 156.0.8078.47 (Linux)
- Google Chrome desktop versions before 156.0.8078.47 or 156.0.8078.48 (Windows and macOS)
- Chromium-based browsers that ingest the affected Chromium code (for example Microsoft Edge), per secondary sources
Fixed in
- Linux: Chrome 156.0.8078.47 or later
- Windows and macOS: Chrome 156.0.8078.47 or 156.0.8078.48 or later
- Exact fixing build for this specific bug: Unknown.
Workaround
- Unknown. No vendor-documented workaround found.
- Until patched, consider restricting DevTools via an enterprise policy; verify the policy name in Google's Chrome Enterprise documentation first.
Exploitation
- CISA KEV: not listed (per third-party tracker).
- Public proof of concept: none found.
- CISA SSVC: Exploitation none, Automatable no, Technical Impact total.
Our recommendation
- Update Chrome to version 156.0.8078.47 or later (Windows and macOS: 156.0.8078.48 where applicable) on all workstations.
- Confirm the installed version on each machine and restart the browser, as a pending update does not mean the old process has stopped.
- Update other Chromium-based browsers such as Microsoft Edge and track their security advisories.
- Apply the full Chrome 156 release, which fixes further security issues, within the normal patch cycle.
