CVE-2023-22384

Memory corruption via unchecked FMQ data copy

Published Oct 3, 2023 · Updated Feb 27, 2025

Memory corruption in Qualcomm Snapdragon VR Service allows local users with high privileges to trigger an out-of-bounds write via FMQ data. The service copies data received through Fast Message Queue without checking the input size, causing memory to be written beyond its intended buffer. Exploitation requires local, high-privilege access; Qualcomm has not disclosed whether the corruption yields code execution or only service failure.
