Memory disclosure via unvalidated firmware IPC message
Published Dec 2, 2024 · Updated Dec 2, 2024
Buffer over-read in Qualcomm Snapdragon NPU drivers allows local users to disclose memory through a malformed firmware IPC message. The NPU driver processes a firmware-supplied IPC message without validating its fields or length, causing a read beyond the intended buffer. Exploitation requires local low-privileged access; the published record does not identify the exposed data or explain how the malformed message is induced.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
