Memory corruption via stale DSP memory mappings
Published Oct 7, 2024 · Updated Oct 21, 2025
A use-after-free in Qualcomm Snapdragon DSP Services allows local users with low privileges to corrupt memory on affected chipsets. DSP Services access freed memory while maintaining mappings of high-level operating-system memory, leaving stale mapping state available for reuse. Exploitation requires local low-privilege access and no user interaction, and it can compromise data and interrupt the affected device.
