What is CVE-2025-49140?

The Pion Interceptor is a framework designed for RTP/RTCP communication software but contains a vulnerability in its RTP packet factory. Users of versions v0.1.36 to v0.1.38 may experience a panic if crafted RTP packets are sent, leading to potential disruptions in Pion-based SFU environments. To remedy this issue, it is recommended to upgrade to version v0.1.39 or later, which includes enhanced validation of the packet length and error handling to prevent crashes. For those unable to upgrade immediately, manual patching or filtering of packets with set P-bits (with padLen of zero or exceeding the remaining payload) is advised.

Affected Version(s)

interceptor >= 0.1.36, < 0.1.39
