Description
CVE-2025-64169 is a vulnerability in Wazuh versions from 3.7.0 up to but not including 4.12.0. The issue arises because the fim_alert() function does not check if oldsum->md5 is NULL before dereferencing it. This can allow a compromised agent to send a crafted message that causes the analysisd process to crash. The vulnerability has been fixed in version 4.12.0.
