What it is

🔥 A clever stack overflow in Tenda AC10 could let attackers pull off a Denial of Service or even execute arbitrary code with just the right input!

Attackers could wreak havoc by crashing your device or taking complete control over it. Imagine your once-functional network being reduced to a standstill, all because of a single malicious payload—absolutely devastating!
