OS fingerprinting helps attackers identify the operating system and version running on a target host. This allows them to:

Determine potential vulnerabilities

Choose appropriate exploits for the OS version and configuration

Bypass ineffective defenses

From CEH v13 Courseware:

Topic: Active and Passive OS Fingerprinting

CEH v13 Study Guide states:
