SMB Impact
How this vulnerability affects a real small business
1
How this breaks an SMB

Operating system vulnerability enables privilege escalation or remote code execution — giving attackers full control over affected machines within the network.

2
Typical real-world scenario

Initial foothold (phishing or exposed service) triggers OS exploit. Domain admin privileges are obtained. Ransomware is deployed network-wide overnight.
