What is CVE-2026-85150?

A NULL pointer dereference vulnerability has been discovered in the GStreamer RTSP support library. This issue arises when parsing an Authorization or WWW-Authenticate header that utilizes Digest authentication. Specifically, the vulnerability is triggered by a carefully crafted parameter with improper whitespace, leading to an internal length calculation underflow. This condition can result in a denial of service (DoS) attack, causing the application to crash. An unauthenticated remote attacker can exploit this vulnerability by sending a specially formatted request to an RTSP server with authentication enabled, or by taking advantage of a vulnerable RTSP client when connected to a malicious RTSP server. There are no verified impacts on confidentiality or integrity associated with this vulnerability.
