KnoxGuardManager EUVD-2026-42815

KnoxGuardManager is a privileged system component within Samsung Knox, Samsung's hardware-backed enterprise mobile security platform. Knox Guard specifically enables carriers and enterprise administrators to enforce device lifecycle controls - including enrollment persistence, conditional locking, and remote management state - that are intended to survive factory resets and resist tampering by device users. The vulnerability involves inadequate authorization enforcement when accessing or modifying the persistence configuration managed by KnoxGuardManager. The 'Authentication Bypass' tag indicates the component fails to verify that the calling process holds the required privilege level before permitting configuration changes. The CVSS 4.0 AT:P (Attack Requirements: Present) metric signals that a specific precondition - most likely an active Knox Guard enrollment state - must be in place on the target device. No CWE was assigned in the source data, so the root cause class beyond 'improper authorization' is not formally classified.
