Use after free in Sharing in Google Chrome on on iOS prior to 153.0.8010.36 allowed a remote attacker to execute arbitrary code outside the sandbox via crafted network traffic. (Chromium security severity: Medium)
AnalysisAI
Remote code execution in Google Chrome on iOS before 153.0.8010.36 stems from a use-after-free in the Sharing component (CWE-416), letting a remote attacker who lures a victim to crafted network content execute arbitrary code outside the browser sandbox. Google has shipped a patched Chrome build; no public exploit is identified at time of analysis, and Google/Chromium rated the underlying bug 'Medium' severity even though the assigned CVSS base score is 9.6.
