CVE-2026-54632 is a denial-of-service vulnerability in SIPSorcery affecting handling of malformed UDP traffic on the RTP/ICE socket. A specially crafted malformed UDP packet can trigger an unhandled exception during packet processing, including STUN parsing associated with ICE connectivity checks. Because the exception is not safely contained in the UDP receive path, the affected RTP or WebRTC media session can be terminated instead of the malformed packet being discarded.
