Memory corruption via unvalidated WMI command index
Published Sep 5, 2023 · Updated Aug 2, 2024
Improper array-index validation in Qualcomm WLAN HAL firmware allows local users to corrupt memory through a crafted WMI payload. WLAN HAL accepts command parameters from untrusted WMI payloads without adequately validating an array index; Qualcomm does not disclose the affected array or subsequent memory operation. Exploitation requires local low-privilege access and no user interaction; the documented consequence is memory corruption.
