CVE-2024-23360

Memory corruption via unauthorized GPU register access

Published Jun 3, 2024 · Updated Aug 1, 2024

Improper access control in Qualcomm Snapdragon firmware allows local users to corrupt memory while creating an LPAC client. The LPAC engine permits the client-creation path to access GPU registers, crossing the intended register-access boundary and corrupting memory. Local execution is required; Qualcomm reports no privileges or user interaction are needed, and successful exploitation can compromise data and interrupt the device.
