CVE-2026-42469: n/a
Buffer overflow vulnerability in Open Vehicle Monitoring System 3 (OVMS3) 3.3.005. In canformat_canswitch.cpp the parser does not properly validate a CANswitch DLC value, allowing remote attackers to cause a denial of service or possibly execute arbitrary code via crafted CANswitch frames.
AI Analysis
Technical Summary
This vulnerability involves a buffer overflow in the OVMS3 3.3.005 software, specifically in the CANswitch frame parser component (canformat_canswitch.cpp). The parser fails to properly validate the DLC (Data Length Code) value of CANswitch frames, which can be exploited remotely by attackers to trigger a denial of service or possibly execute arbitrary code. OVMS3 is a cloud-hosted service, and the vendor manages remediation for this environment. Although a patch is available, no detailed vendor advisory or patch link is provided in the data.
Potential Impact
Successful exploitation could lead to denial of service or remote code execution within the OVMS3 environment. Given the cloud service nature of OVMS3, such an impact could affect availability and potentially compromise the integrity of the service. There are currently no known exploits in the wild, reducing immediate risk.
Mitigation Recommendations
Since OVMS3 is a cloud-hosted service and a patch is available, the vendor is expected to manage remediation server-side. Users should verify with the vendor advisory for confirmation of patch deployment and ensure their service instances are updated accordingly. No additional user action is specified or required at this time.
