The product does not validate, or incorrectly validates, a certificate. As an impact it is known to affect integrity. CVE summarizes:

A logic vulnerability was found in GStreamer's webrtcbin component. The _check_sdp_crypto() function contains an inverted boolean condition that causes it to accept remote SDP offers or answers that lack the required a=fingerprint attribute, while incorrectly rejecting those that include it. An attacker with the ability to intercept and modify WebRTC signaling messages could exploit this to bypass the SDP-level DTLS certificate fingerprint binding, weakening defenses against man-in-the-middle attacks on media streams.
