> Four remotely exploitable memory and handler flaws in Honeywell OneWireless WDM allow information exposure, denial of service, or remote code execution.

Honeywell OneWireless Wireless Device Manager (WDM) contains four critical vulnerabilities in its Control Data Access (CDA) component affecting versions prior to R322.5 and R331.1. The flaws include buffer overread (CVE-2025-2521, CVSS 8.6), sensitive data reuse in buffers (CVE-2025-2522, CVSS 6.5), integer underflow enabling arithmetic failures (CVE-2025-2523, CVSS 9.4), and improper packet handler deployment (CVE-2025-3946, CVSS 8.2). All four vulnerabilities are remotely exploitable with no authentication required and low attack complexity. Successful exploitation could yield information disclosure, denial of service, or remote code execution. OneWireless WDM is deployed in chemical and energy critical infrastructure worldwide. CISA reports no known active exploitation in the wild as of the advisory date, but the high CVSS scores and ease of remote exploitation warrant immediate patching.
