Google Chrome: Memory corruption in Canvas allows sandboxed code execution
Summary
Google Chrome versions before 156.0.8078.47 contain a memory corruption flaw (CWE-119) in the Canvas component. A remote attacker can potentially execute arbitrary code inside the browser sandbox by luring a user to a crafted HTML page. User interaction is required, and no public exploit or known exploitation was found. The NVD CVSS score is 8.8 (High).
Affected
- Google Chrome desktop before 156.0.8078.47 (per the CVE description)
- The official CVE record lists the range inconsistently (156.0.8078.47 to < 156.0.8078.47); verify against the vendor advisory
Fixed in
- Linux and Android: 156.0.8078.47
- Windows and macOS: 156.0.8078.47/.48 (secondary sources; verify against the vendor advisory)
Workaround
Unknown. No vendor-specific mitigation is known; apply the update and restart the browser.
Exploitation
- No known exploitation in the wild.
- No public proof of concept found.
Our recommendation
- Update Google Chrome (and Chromium-based Edge, if used) to the fixed version on all endpoints.
- Restart the browser after the update and verify the version.
- Check Chromium-based products and Linux distributions for their own updates.
- Prioritise unmanaged or slow-updating workstations.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
