CVE-2026-13196: CWE-787 Out-of-bounds Write in KUNBUS piControl
Nozomi Networks Labs identified a CWE-787: Out-of-bounds Write vulnerability in the process-image management functionality of KUNBUS piControl in version 2.6.2 that allows a local authenticated attacker with device configuration access to write attacker-controlled data outside the bounds of the process-image buffer and corrupt adjacent kernel memory, resulting in kernel memory corruption and denial of service, by supplying crafted device configuration data and crafted input through the piControl character device.
AI Analysis
Technical Summary
Nozomi Networks Labs identified a CWE-787 out-of-bounds write vulnerability in the process-image management functionality of KUNBUS piControl version 2.6.2. A local attacker with authenticated access to device configuration can write data outside the bounds of the process-image buffer, corrupting adjacent kernel memory. This can result in kernel memory corruption and denial of service. The attack vector requires supplying crafted device configuration data and input via the piControl character device.
Potential Impact
Successful exploitation leads to kernel memory corruption and denial of service on the affected device. The attacker must have local authenticated access with device configuration privileges. There is no indication of remote exploitation or code execution from the provided data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restrict local authenticated access to trusted users only.
