CVE-2025-47349

Memory corruption via out-of-range DSP pointer offset

Published Oct 9, 2025 · Updated Oct 9, 2025

Memory corruption in the Qualcomm Snapdragon DSP service allows local users with low privileges to corrupt memory through an escape call. The DSP service uses an out-of-range pointer offset while processing the escape call, causing the corruption. Qualcomm has not published the resulting behavior beyond memory corruption, and exploitation requires local low-privileged access.
