Google Chrome: Improper input validation in Skia allows code execution
Summary
Google Chrome prior to 156.0.8078.79 contains an improper input validation flaw in the Skia graphics library. A remote attacker can craft an HTML page that could potentially execute arbitrary code outside the browser sandbox. The attack requires that a user visits the crafted page, and no authentication is needed.
Affected
- Google Chrome prior to 156.0.8078.79 (desktop, Windows, macOS, Linux)
- Other Chromium-based browsers: Unknown.
Fixed in
- Google Chrome 156.0.8078.79 (Linux)
- Google Chrome 156.0.8078.79 or .80 (Windows, macOS), released 29 October 2026
Workaround
Unknown. No workaround is documented; the fix is a browser update.
Exploitation
- No exploitation reported as of 30 October 2026 according to available sources.
- No public proof-of-concept indexed as of 29 October 2026.
- Not listed in CISA KEV.
- Information is provisional, based on sources from one day after disclosure.
Our recommendation
- Update Google Chrome and all Chromium-based browsers to the fixed versions immediately.
- Force a browser restart after the update so the new version takes effect.
- Deploy updates via managed policy or MDM and check unmanaged devices.
- Verify Linux hosts receive the new repository build, as stale package indexes may show older versions.
- Monitor vendor advisories for further information on exploitation.
