UBUNTU-CVE-2026-110655 (CVE-2026-110655)

Vulnerability from osv_ubuntu – Published: 2026-10-15 00:00 – Updated: 2026-10-22 20:44 – Source website

Details

miniupnpc through 2.3.3 contains a one-byte heap out-of-bounds read vulnerability in the minixml parseatt function that allows malicious UPnP gateways to read past buffer bounds via crafted replies. Attackers on the local network can spoof a gateway serving device descriptions or SOAP responses ending in '=' to crash the client.

Severity

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
