Remote, unauthenticated, but needs the victim to load a crafted page (UI:R); I keep S:U since the 'outside sandbox' escape is only 'potential', yielding ~8.8 rather than 9.6.

Use after free in Dawn in Google Chrome on on Android prior to 153.0.8010.52 allowed a remote attacker to potentially execute arbitrary code outside the sandbox via a crafted HTML page. (Chromium security severity: Critical)

AnalysisAI

Use-after-free in the Dawn (WebGPU) component of Google Chrome on Android before 153.0.8010.52 allows a remote, unauthenticated attacker to potentially execute arbitrary code outside the browser sandbox when a victim renders a crafted HTML page. Exploitation requires the user to load attacker-controlled content (CVSS 9.6, AV:N/AC:L/PR:N/UI:R), and Google rates the bug Chromium security severity Critical; the only affected configuration is Chrome on Android below the fixed 153.0.8010.52 build, and devices already updated are not exposed. …
