🚨 A sneaky race condition lets attackers tamper with memory at the worst possible moment! This vulnerability in Core is a ticking time bomb. 🔥 Think of it like a busy restaurant where the chef is trying to serve a dish but is interrupted by a server who misreads the order: the dish goes out wrong because no one double-checked the details! An attacker could exploit this condition to manipulate memory, leading to potentially devastating consequences like system crashes, data leaks, or even remote code execution. Imagine a rogue chef altering the food just before it’s served — absolute chaos!
