What is CVE-2025-64169?

The Wazuh platform, used for threat prevention and detection, is vulnerable due to a flaw in the fim_alert() function. The implementation fails to properly check if oldsum->md5 is NULL before dereferencing it. This oversight could allow a malicious agent to crash the analysisd service by sending a specially crafted message to the Wazuh manager, potentially disrupting security operations. This vulnerability affects versions 3.7.0 through 4.11.0 and has been resolved in version 4.12.0.

Affected Version(s)

wazuh >= 3.7.0, < 4.12.0
