Memory disclosure via invalid TrustZone transfers
Published Jun 14, 2022 · Updated Aug 3, 2024
Improper input validation in the TrustZone memory transfer interface on Qualcomm Snapdragon Compute SD850 and SDXR1 allows local users to read memory. Qualcomm identifies the affected locus as the TrustZone memory transfer interface but does not disclose which input property is accepted or how the transfer exposes memory. The flaw is locally reachable without prior privileges or user interaction and affects confidentiality only; no memory modification or service interruption is reported.
