CVE-2025-47367

Local memory corruption during WinBlast IOCTL processing

Published Nov 4, 2025 · Updated Nov 4, 2025

Out-of-bounds write in the WinBlast driver in Qualcomm Snapdragon platforms allows local users to corrupt memory through crafted IOCTL requests. The driver accesses a buffer outside its bounds during IOCTL processing, but Qualcomm has not disclosed the affected routine or omitted validation. Low-privileged local access is required, and no user interaction is needed; the resulting driver corruption can compromise the operating environment.
