DescriptionCVE.org

Inappropriate implementation in AI in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

Sandbox escape in Google Chrome desktop before 150.0.7871.47 lets an attacker who has already compromised the renderer process break out of the security sandbox using a crafted HTML page, elevating from a contained renderer to broader host access. Rooted in CWE-669 (incorrect resource transfer between spheres) within Chrome's AI component, it carries a CVSS 8.3 (scope-changed) rating despite Google's own 'Low' Chromium severity, reflecting the fact that it is a second-stage escape rather than a standalone entry point. …
