CVE-2026-107696
Description
A flaw was found in FFmpeg. When processing media streams using the Real-Time Streaming Protocol (RTSP), the client fails to enforce a limit on redirection responses. A malicious or compromised RTSP server can repeatedly redirect requests back to itself or another host, trapping the application in an infinite loop. This issue can result in a Denial of Service (DoS) by consuming excessive system CPU resources and causing the application to hang.
Statement
This vulnerability is rated as having a Moderate impact for Red Hat environments because exploitation requires an application or client to initiate a connection to an untrusted external RTSP source. Repeated redirection responses from an adversarial server can cause the receiving process to enter an endless loop and consume CPU resources, leading to a denial of service, but this does not compromise system confidentiality or integrity. In typical Red Hat deployments, multimedia processing workloads do not consume unverified network streams by default, which bounds the overall blast radius.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
