CVE-2026-74045: Wazuh heap buffer overflow in fim_generate_alert()

CVE-2026-74045 · Severity: high · CVSS 7.1 · Published 2026-10-13

Wazuh is a security monitoring platform that analyzes events from distributed agents to detect threats. An enrolled agent can send a malicious FIM (file integrity monitoring) event to the manager that corrupts the analysis engine's memory and crashes it, causing a complete outage of threat detection across all monitored systems until the service is restarted.

Technical details

A heap buffer overflow in wazuh-analysisd's fim_generate_alert() function occurs because full_log is allocated based on input length but written using snprintf with OS_MAXSTR (65535) as the size limit, causing writes past the allocation when generated alert text exceeds the smaller allocation. An enrolled agent can send a crafted FIM syscheck event with inflated JSON values (such as 9e18 exponents) that expand during text generation, reliably corrupting heap metadata and terminating the analysis daemon.
