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
CVE-2026-42469 is a buffer overflow vulnerability in OVMS3 3.3.005 caused by improper validation of the CANswitch DLC value in the canformat_canswitch.cpp parser. This vulnerability enables remote attackers to trigger denial of service or possibly execute arbitrary code via specially crafted CANswitch frames. The vulnerability is present in a cloud-hosted service, and a patch is available with remediation managed by the vendor.
Potential Impact
Successful exploitation can lead to denial of service or potentially arbitrary code execution on the affected OVMS3 cloud service. This could disrupt vehicle monitoring operations or compromise system integrity. No known active exploits have been reported.
Mitigation Recommendations
Since OVMS3 is a cloud service, the vendor manages remediation and applies patches server-side. Users should verify with the vendor's advisory for confirmation of patch deployment. No additional user action is required unless otherwise directed by the vendor.
