Answer in brief
CVE-2026-44251 records a Medium severity (CVSS 6.5) vulnerability in Wazuh : size_t underflow in msgs.c ReadSecMSG causes wazuh-remoted DoS and potential heap overflow via crafted agent message. The current sources do not mark it as known exploited. The current feed maps wazuh/wazuh (generic). Check affected ranges and fixed versions before updating.

HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 6.5. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 3.0.0 and above, prior to 4.14.5, a size_t integer underflow in os_crypto/shared/msgs.c:389 allows any enrolled Wazuh agent to crash the wazuh-remoted process on the manager, immediately disconnecting all agents from the manager. A second code path reached by the same underflow may allow heap memory corruption. This issue has been fixed in version 4.14.5.
