Local memory corruption via invalid DDI buffer
Published Aug 6, 2025 · Updated Aug 6, 2025
Improper array-index validation in Qualcomm Snapdragon DSP Service allows local users to corrupt memory through an invalid DDI buffer. The DSP Service processes a DDI call’s invalid buffer without adequately validating an array index, permitting out-of-bounds memory access. Exploitation requires local low-privilege access and no user interaction; the public record does not disclose whether the corruption causes a crash, code execution, or another concrete outcome.
