Local information disclosure via variable-time SUI comparisons
Published Apr 16, 2020 · Updated Aug 5, 2024
Information exposure in Qualcomm Snapdragon platform firmware allows local users to obtain sensitive data through timing observations. Closed-source SUI logic uses non-time-constant comparison functions, causing input-dependent execution times that expose a measurable side channel. Exploitation requires local low-privileged execution and repeated timing measurements; the documented consequence is disclosure that can facilitate SUI corruption, not code execution.
