Memory disclosure via DPP action-frame buffer over-read
Published Jun 6, 2023 · Updated Aug 2, 2024
Buffer over-read in Qualcomm WLAN HOST firmware allows adjacent unauthenticated attackers to disclose memory via a crafted DPP action frame. When the host sends a DPP action frame to a peer with an invalid source address, the frame-processing path reads beyond its intended buffer. Exploitation requires wireless proximity and affects confidentiality only, with no reported integrity or availability impact.

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.
