CVE-2026-57559

Local memory corruption via use-after-free service requests

Published Oct 6, 2026 · Updated Oct 6, 2026

Use-after-free in Qualcomm Snapdragon DSP_Services allows local users to corrupt memory by submitting service requests. Qualcomm identifies the service-request processing path but does not disclose the affected function or the request sequence that accesses freed storage. The published attack path requires low-privilege local access; the record does not establish a network-reachable path or a specific post-corruption outcome.
