Technical impact
A buffer overflow flaw exists in the Panasonic Industry USB Driver for MINAS A5/A6. When USB traffic is processed by the driver, an attacker can cause a memory corruption that leads to Windows terminating its operation, resulting in a system crash and effectively denying service to the affected machine. The vulnerability is a classic buffer overflow (CWE‑120).
Affected Systems
All Windows installations of PANASONIC PANATERM for Multi, PANATERM v6, PANATERM v7, or RTEX LogReader that include the Panasonic USB driver are vulnerable. The description does not limit the impact to specific versions, so any released product containing the driver is at risk until patched.
Risk and Exploitability
The CVSS score of 6.8 indicates moderate severity. The EPSS score of < 1% indicates a very low exploitation probability, and the vulnerability is not listed in the CISA KEV catalog. The likely attack vector is local; an attacker would need to provide a maliciously crafted USB device or gain local access to engage high privileges. Successful exploitation will crash Windows but does not provide remote code execution or broader lateral movement according to the available information.
