CVE-2026-59692: GStreamer DTLS Plugin Stack Buffer Overflow Leading to DoS

A stack buffer overflow vulnerability, CVE-2026-59692, exists in GStreamer's DTLS plugin, allowing a remote unauthenticated attacker to cause a denial of service by sending a crafted certificate with an oversized Subject Distinguished Name during a DTLS handshake, which the plugin prints into a fixed-size stack buffer without bounds checking, leading to a process crash.
