CVE-2026-1108
Published: 18 January 2026
Summary
CVE-2026-1108 is a medium-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Cijliu Librtsp. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 6.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Threat & Defense at a Glance
Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.
Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.
Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.
Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Local buffer overflow (CWE-119/120) with low-priv access directly enables exploitation for privilege escalation via memory corruption leading to code execution or DoS.
NVD Description
A security vulnerability has been detected in cijliu librtsp up to 2ec1a81ad65280568a0c7c16420d7c10fde13b04. The affected element is the function rtsp_rely_dumps. The manipulation leads to buffer overflow. An attack has to be approached locally. This product is using a rolling release to…

Deeper analysisAI
CVE-2026-1108 is a buffer overflow vulnerability in the cijliu librtsp library, specifically affecting the rtsp_rely_dumps function up to commit hash 2ec1a81ad65280568a0c7c16420d7c10fde13b04. The library uses a rolling release model for continuous delivery, so no specific affected or patched version details are available. It is associated with CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-120 (Buffer Copy without Checking Size of Input), and carries a CVSS v3.1 base score of 5.3 (AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).
Exploitation requires local access with low privileges, low attack complexity, and no user interaction. A successful attack triggers the buffer overflow in rtsp_rely_dumps, potentially allowing limited impacts on confidentiality, integrity, and availability, such as partial data exposure, modification, or denial of service within the local scope.
Advisories from VulDB indicate the vendor was contacted early but provided no response, with no patches or updated releases disclosed due to the rolling release nature.
