What is CVE-2026-14935?
CVE-2026-14935 is a low-severity vulnerability in Red Hat Enterprise Linux 10, published on 7 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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.
Weakness: CWE-670
