CVE-2024-53020Network attack vector

Memory disclosure via malformed RTP header extension

Published Jun 3, 2025 · Updated Jun 3, 2025

Buffer over-read in Qualcomm Snapdragon Data Network Stack & Connectivity allows remote attackers to disclose memory via malformed RTP packets. The RTP decoder reads beyond the packet buffer while processing an invalid header extension; Qualcomm has not published the responsible function or validation error. No privileges or user interaction are required, and successful processing exposes memory contents beyond the received packet.
