Memory corruption via unchecked Core parameter length
Published Sep 9, 2021 · Updated Aug 3, 2024
Buffer overflow in Qualcomm Snapdragon trusted applications allows local users to corrupt memory through oversized Core parameters. The Core component handles parameters without checking their lengths, allowing oversized input to overrun a buffer. Local access to a trusted application is required; the overflow can alter protected data or interrupt execution within the affected security scope.
