CVE-2026-1110
Published: 18 January 2026
Summary
CVE-2026-1110 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 4.8 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 8.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2026-1110 is a buffer overflow vulnerability (CWE-119, CWE-120) in the rtsp_parse_method function of the cijliu librtsp library, affecting commits up to 2ec1a81ad65280568a0c7c16420d7c10fde13b04. The library employs continuous delivery with rolling releases, making specific details on affected or updated versions unavailable.
The vulnerability 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). A local attacker with low privileges can exploit it on the host system, potentially achieving low-level impacts on confidentiality, integrity, and availability via buffer overflow manipulation.
Advisories note that the vendor was contacted early regarding disclosure but provided no response. No patches or official mitigations are available due to the rolling release model. Details are documented in VulDB entries and a GitHub markdown file analyzing the rtsp_parse_method flaw.

Why these techniques?
Local buffer overflow in library parsing function directly enables local privilege escalation via memory corruption.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of all input to rtsp_parse_method to reject malformed data before buffer overflow occurs.
Enforces memory protections (e.g., ASLR, NX) that block exploitation of the buffer overflow in the affected library function.
Restricts local user privileges so that even successful overflow yields only minimal confidentiality/integrity/availability impact on the host.
