Anonymous

• CVE-2025-10200: A use-after-free flaw in Chrome’s ServiceWorker component. Exploiting this bug could allow remote attackers to execute arbitrary code and gain full control of the system.

• CVE-2025-10201: An inappropriate implementation issue in Chrome’s Mojo IPC framework, which could lead to privilege escalation or bypass of security mechanisms.

IMPACT

• Successful exploitation may result in:
o Remote code execution
o Privilege escalation
o Complete system compromise

Given the widespread use of Chrome, exploitation attempts are highly likely once details become public.

MITIGATION/SOLUTION

• Immediate Action Required: Update Google Chrome to the latest stable release:
o Navigate to: Help → About Google Chrome → Update
o Restart the browser after update completion
• Ensure auto-updates are enabled for future patch cycles.

RECOMMENDATION

• Apply the update immediately across all endpoints in your environment.
• Monitor for unusual browser activity and investigate suspicious network requests.
• Educate end-users to restart their browsers after updates to ensure patches are applied.
• Incorporate browser patching into your organization’s regular vulnerability management cycle.
