Firmware memory corruption via invalid WNM frame length
Published Feb 9, 2023 · Updated Aug 3, 2024
Stack-based buffer overflow in Qualcomm WLAN firmware allows remote attackers to corrupt memory through an invalid-length WNM frame. The proprietary WLAN handler uses the invalid frame length in a stack-buffer operation that writes beyond the buffer boundary. No authentication or user interaction is required, and successful exploitation corrupts WLAN firmware memory on an affected chipset.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
