CVE-2026-37541: n/a
Buffer overflow vulnerability in Open Vehicle Monitoring System 3 (OVMS3) 3.3.005. In canformat_gvret.cpp, the length field in GVRET binary data is not properly validated, allowing remote attackers to cause a denial of service or possibly execute arbitrary code via crafted GVRET frames.
AI Analysis
Technical Summary
This vulnerability involves improper validation of the length field in GVRET binary data within OVMS3 3.3.005's canformat_gvret.cpp. Due to this buffer overflow (CWE-121), remote attackers can trigger denial of service or possibly execute arbitrary code by crafting malicious GVRET frames. The vulnerability is remotely exploitable without privileges or user interaction, with a critical CVSS 3.1 base score of 10. OVMS3 is a cloud service, and the vendor manages remediation for this environment. Patch availability is confirmed, though no direct patch links or detailed remediation levels are provided.
Potential Impact
Successful exploitation can lead to a complete denial of service or remote code execution on the affected OVMS3 cloud service, impacting confidentiality, integrity, and availability at a critical level. The vulnerability requires no privileges or user interaction and can be triggered remotely over the network.
Mitigation Recommendations
Since OVMS3 is a cloud-hosted service, the vendor is responsible for applying patches and managing remediation server-side. Users should verify with the vendor advisory for confirmation of patch deployment. No additional user action is specified or required at this time.
