Technical Analysis

This vulnerability in Google Chrome affects the ANGLE component, where insufficient validation of untrusted input can lead to arbitrary code execution when processing crafted HTML content. The affected versions are those prior to 148.0.7778.216. The issue was publicly disclosed on May 28, 2026.
