CVE-2026-1108 identifies a buffer overflow vulnerability in the cijliu librtsp library, specifically within the rtsp_rely_dumps function. This flaw arises from improper handling of input data, leading to memory corruption when the function processes certain RTSP-related data. The vulnerability requires local access with low privileges (PR:L), no user interaction (UI:N), and has low attack complexity (AC:L). The impact affects confidentiality, integrity, and availability to a limited extent (VC:L, VI:L, VA:L). The product follows a rolling release model, which means traditional versioning is not used, complicating identification of affected versions and patch management. The vendor has not responded to early disclosure attempts, and no patches or updates are currently available. No known exploits have been reported in the wild, but the vulnerability could be leveraged by an attacker with local access to execute arbitrary code or cause denial of service. The vulnerability scoring reflects a medium severity level (CVSS 4.8), indicating moderate risk primarily due to the requirement for local access and the limited scope of impact.

For European organizations, the primary impact lies in environments where the cijliu librtsp library is deployed, typically in multimedia streaming or real-time communication applications that use RTSP protocols. The buffer overflow could allow a local attacker to execute arbitrary code, escalate privileges, or cause service disruptions, potentially affecting sensitive data confidentiality and system availability. Organizations with internal systems or devices running librtsp could face operational disruptions or data breaches if exploited. Given the local access requirement, remote exploitation risk is low, but insider threats or compromised local accounts could leverage this vulnerability. The lack of vendor response and patches increases the risk window, necessitating proactive mitigation. Critical infrastructure or media companies in Europe using RTSP streaming solutions may be particularly sensitive to such disruptions.

European organizations should first inventory and identify any use of the cijliu librtsp library within their environments, focusing on applications handling RTSP streams. Since no patches are currently available, mitigation should include restricting local access to trusted users only, enforcing strict access controls and monitoring for unusual activity on systems running librtsp. Employ application sandboxing or containerization to limit potential damage from exploitation. Consider replacing or updating the RTSP handling components with alternative libraries that have active maintenance and security support. Implement host-based intrusion detection systems (HIDS) to detect anomalous behavior indicative of exploitation attempts. Regularly review and update internal security policies to minimize local privilege escalation risks. Engage with the vendor or open-source community for updates or patches and monitor vulnerability databases for any emerging exploit code or fixes.
