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 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-2026-1108 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. Detailed analysis is available in the GitHub reference at https://github.com/fizz-is-on-the-way/vuls_protocol/blob/main/librtsp_rtsp_rely_dumps/librtsp_rtsp_rely_dumps.md and VulDB entries at https://vuldb.com/?ctiid.341700, https://vuldb.com/?id.341700, and https://vuldb.com/?submit.732598.

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.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires size and bounds checking on all input to rtsp_rely_dumps, eliminating the unchecked buffer copy that triggers the overflow.
Enforces runtime memory protections (e.g., non-executable stacks, ASLR) that block exploitation of the buffer overflow in the librtsp library.
Restricts local processes and users to least privilege, reducing the impact an attacker can achieve after triggering the overflow.
