CVE-2026-1108 identifies a buffer overflow vulnerability in the cijliu librtsp library, specifically within the function rtsp_rely_dumps. This function improperly handles input data, leading to a buffer overflow condition when manipulated locally. The vulnerability requires an attacker to have local access with low privileges, and no user interaction is necessary to trigger the flaw. The buffer overflow can potentially allow an attacker to corrupt memory, leading to partial compromise of confidentiality, integrity, and availability of the affected system. The librtsp library is distributed via a rolling release model, which means that specific version numbers are not fixed, and updates are continuously delivered. This complicates tracking which exact releases are vulnerable or patched. The vendor has been contacted but has not responded or provided a patch, leaving users without an official remediation path. The CVSS v4.0 base score is 4.8, reflecting medium severity due to the local attack vector and limited scope of impact. No known exploits have been reported in the wild, but the vulnerability remains a risk for environments where librtsp is deployed and local access can be obtained. The lack of vendor engagement and patch availability increases the importance of mitigation through access controls and monitoring.

For European organizations, the impact of CVE-2026-1108 depends largely on the deployment context of the cijliu librtsp library. Organizations using librtsp in local streaming, media processing, or embedded systems could face risks of memory corruption leading to potential data leakage, unauthorized code execution, or service disruption. The local attack requirement limits remote exploitation, but insider threats or compromised local accounts could exploit this vulnerability. Confidentiality, integrity, and availability could be partially impacted, potentially affecting sensitive media streams or related services. Given the rolling release nature and lack of vendor patching, organizations may face prolonged exposure. The impact is heightened in sectors with critical media infrastructure, such as broadcasting, telecommunications, and video surveillance, which are prevalent in Europe. Additionally, organizations with strict regulatory requirements around data protection (e.g., GDPR) must consider the risk of data compromise. The absence of known exploits reduces immediate threat but does not eliminate risk, especially as attackers may develop exploits over time.

1. Restrict local access to systems running cijliu librtsp to trusted users only, employing strict access controls and monitoring. 2. Employ host-based intrusion detection systems (HIDS) to detect anomalous behavior or memory corruption attempts related to librtsp processes. 3. Where feasible, isolate librtsp-dependent applications in sandboxed or containerized environments to limit potential damage from exploitation. 4. Monitor vendor channels and security advisories closely for any forthcoming patches or updates, given the rolling release model. 5. Consider replacing cijliu librtsp with alternative RTSP libraries that have active maintenance and security support if local access cannot be sufficiently controlled. 6. Conduct regular code audits and penetration testing focusing on local privilege escalation vectors involving streaming components. 7. Implement strict logging and alerting on local user activities to detect potential exploitation attempts early. 8. Educate internal users about the risks of local exploitation and enforce least privilege principles to minimize attack surface.
