What is CVE-2025-65102?

A vulnerability exists in PJSIP, a widely used multimedia communication library, where improper handling of the Opus audio codec can lead to a memory overwrite. Specifically, when processing audio streams, the decoder's ptime may conflict with varying input frame lengths, resulting in the potential zero-filling of input frames. This can cause unexpected application termination, posing a significant risk to users relying on the Opus codec for audio transmission. The issue has been addressed in version 2.16 of PJSIP, and users are strongly encouraged to update to this version to mitigate any security risks.
