This vulnerability is particularly dangerous because it can be exploited remotely and leverages a pre-compromised state.","exploitability":"Exploitation requires a remote attacker to first compromise the renderer process, making it moderately difficult but possible with a follow-up attack vector; the attacker needs to craft a malicious HTML page that triggers the race condition.","blast_radius":"If exploited, this vulnerability could allow attackers to execute arbitrary code on the victim's system with the privileges of the Chrome process, potentially leading to full system compromise or data exfiltration.","remediation":"Upgrade to Google Chrome version 155.0.8059.39 or later to remediate this race condition vulnerability.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["browser","sandbox-escape","race-condition"],"model":"garnet-coder","analyzedAt":"2026-10-14T08:55:34.655Z"}}
