Local memory corruption via DSP mapping race
Published Oct 6, 2026 · Updated Oct 6, 2026
Use-after-free in the Qualcomm Snapdragon DSP service allows local users to corrupt memory through concurrent geographic mapping access. The service accesses geographic mapping data while another operation modifies it without proper synchronization, leaving memory in use after it is freed. Exploitation requires low-privilege local access; the published record does not identify a specific crash, data-access, or code-execution outcome.
