What is CVE-2025-65288?

The Mercury MR816v2 contains a buffer overflow vulnerability triggered when the device processes excessively long hostnames from LAN hosts. Insufficient length validation in the code allows for unchecked buffer copies, which can lead to a crash (denial of service) and may also enable remote code execution. Attackers could exploit this flaw by sending carefully crafted hostnames, compromising the device's integrity and functionality.
