CVE-2025-47343

Local memory corruption via video parameter setup

Published Jan 6, 2026 · Updated Jan 6, 2026

Untrusted pointer dereference in Snapdragon video processing allows local users with low privileges to corrupt memory during parameter setup. Qualcomm identifies video-session parameter handling as the locus but has not disclosed the pointer source, dereference operation, or affected read or write path. Exploitation requires local low-privileged access and no user interaction; Qualcomm has not published whether corruption yields a crash, memory access, or code execution.
