Memory corruption via incorrect trusted-application pointer
Published Sep 8, 2021 · Updated Aug 3, 2024
Incorrect type conversion in Qualcomm Snapdragon trusted applications allows local users to cause unintended memory operations. A trusted application receives an incorrect pointer argument and performs memory operations through that pointer without preserving the expected type. Low-privilege local access is required; the public record does not identify which data or trusted-application state can be read, changed, or disrupted.
