CVE-2025-21466 Details
Description
Memory corruption while processing a private escape command in an event trigger.
A buffer over-read vulnerability has been identified in the WLAN firmware of various chipsets used in Qualcomm Snapdragon products. This vulnerability can lead to a transient denial-of-service condition by causing memory corruption when the firmware processes vendor-specific information elements in WLAN frames, particularly for BTM requests. The issue arises from improper handling of length fields, which can create inconsistencies in how data is read and processed, potentially leading to memory being accessed out of bounds.
Qualcomm has released patches for this vulnerability, which can be applied by device manufacturers. Instructions for applying the patch are available in the Qualcomm July 2025 Security Bulletin.
