Protected-data disclosure via unrestricted RPM secure stream
Published Jun 14, 2022 · Updated Aug 4, 2024
Kernel information exposure in Qualcomm Snapdragon platforms allows local users to read secure resources through an RPM secure stream. The SMMU is configured so the RPM secure stream can access any secure resource instead of restricting the stream to its intended mappings. Exploitation requires local low-privileged access; the published impact is disclosure only, without integrity or availability loss.

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.
