CVE-2016-10394

Local device compromise through incomplete xbl_sec checks

Published Nov 26, 2024 · Updated Nov 26, 2024

Improper authentication in Qualcomm Snapdragon xbl_sec on MDM9206, MDM9607, SD 835, SD 845, and SD 850 allows local users to compromise devices. The initial xbl_sec revision lacks unspecified debug-policy features and critical checks; Qualcomm has not disclosed the omitted checks or their exact operation. Exploitation requires local access but no prior privileges or user interaction, and successful abuse compromises device confidentiality, integrity, and availability.
