Who should care

Organizations with Android device fleets running Chrome or WebView-based applications; mobile security teams monitoring browser sandbox integrity; developers using Skia in Android applications

Technical summary

The vulnerability exists in Skia, Chrome's 2D graphics library, where untrusted input validation is insufficient. An attacker with renderer process compromise—typically achieved through a separate vulnerability—can supply malicious input to Skia that bypasses sandbox restrictions. The attack vector requires user interaction to load a crafted HTML page. The fix in Chrome 148.0.7778.216 adds proper validation of Skia input parameters.

Defensive priority

Recommended defensive actions

  • Update Google Chrome on Android to version 148.0.7778.216 or later
  • Monitor for unexpected renderer crashes or sandbox escape indicators in Chrome Android environments
  • Review application sandboxing assumptions for Android WebView components using Skia
  • Apply principle of least privilege to web content processes where feasible
