CVE-2025-47379

Local memory corruption via shared-buffer race

Published Mar 2, 2026 · Updated Mar 2, 2026

Use-after-free in Qualcomm Snapdragon Automotive Audio allows local users with low privileges to corrupt memory through a shared-buffer race. Concurrent assignment and deallocation can leave a stale buffer reference; subsequent use corrupts memory. Local low-privileged access is required, and successful exploitation can compromise confidentiality, integrity, and availability.
