Google CVE-2026-5885

WebML (Web Machine Learning) is a Chrome component that processes machine learning models embedded in web pages. The vulnerability exists in the input validation logic of WebML's HTML parsing mechanism (CWE-20: Improper Input Validation). When WebML processes untrusted HTML content without sufficient validation, an attacker can craft specific HTML structures that cause the parser to read adjacent process memory regions and leak their contents back to the attacker's script context. This is a classic memory safety issue where bounds checking or type validation is insufficient, allowing out-of-bounds memory access during parsing or model interpretation.
