What is CVE-2021-25849?

An integer underflow vulnerability exists in the Moxa Camera VPort 06EC-2V Series, specifically in the userdisk/vport_lldpd component. This issue arises from inadequate validation of the PortID TLV, which can lead to a Denial of Service condition when the camera processes a specially crafted LLDP packet. Successful exploitation may cause the device to become unresponsive, rendering it inoperable until it is manually reset.
