CVE-2026-11535

Unauthenticated device access via Bluetooth authentication defect

Published Jun 12, 2026 · Updated Jun 12, 2026

Missing authentication in vivo PcSuite before 6.2.5 allows physically proximate attackers to access a victim's device over Bluetooth. The affected function accepts a Bluetooth-range connection without authenticating the connecting party, but vivo has not identified the function or protocol operation. Exploitation requires Bluetooth proximity and no privileges or user interaction; vivo does not specify which device data or functions become accessible.
