What it is

🔥 A memory corruption vulnerability in WLAN Host can leave your network wide open like a front door with no lock! Think of it like a restaurant where a rogue waiter can mix up the orders and serve dishes that weren't even on the menu — a single misplaced RRM beacon can lead to chaos in your wireless network. An attacker could potentially exploit this vulnerability to crash the access point or even execute arbitrary code, giving them control over your network. This could lead to unauthorized access to sensitive data and a complete compromise of the network's integrity — absolutely devastating!
