The national cybersecurity agencies recommend reviewing Google’s Stable Channel Update for Desktop notice and applying the necessary updates as they become available. Administrators should verify deployed Chrome versions across all three platforms and update affected installations. The supplied notices do not identify specific CVEs, vulnerability impacts, severity ratings or exploitation activity, so they do not establish whether any flaws are being actively exploited.
