CVE-2025-47352

Memory corruption via improper audio array index validation

Published Nov 4, 2025 · Updated Nov 4, 2025

Array-index validation failure in Qualcomm Snapdragon audio firmware allows local users to corrupt memory during audio streaming operations. Qualcomm maps the flaw to CWE-129 but has not published the affected audio routine, invalid index source, or resulting memory access. The failure requires low local privileges and no user interaction; available disclosures do not establish whether exploitation yields code execution or only a crash.
