What is CVE-2026-125712?

A flaw has been identified in GStreamer’s gst-plugins-base RTCP SDES packet parser. An attacker exploiting this vulnerability can send a malformed SDES entry with a declared length exceeding the actual received packet. This lack of bounds validation in the packet buffer may result in the application's inability to properly handle the data, potentially leading to application crashes or the unintentional exposure of sensitive process memory.
