CVE-2023-28559

Memory corruption via unchecked WMI parameter copy

Published Sep 5, 2023 · Updated Feb 27, 2025

Buffer overflow in Qualcomm Snapdragon WLAN firmware allows local users to corrupt memory through an untrusted WMI payload. The WLAN HAL copies command parameters from the WMI payload without checking whether the input fits the destination buffer. Reaching the flaw requires low-privilege local access and no user interaction; Qualcomm reports memory corruption but does not publish a more specific outcome.
