What it is

⚡ A missing bounds check in KeyInstall could let a crafty local user execute a privilege escalation — no user interaction required! 🎯 Think of it like a careless hotel manager who forgot to check if a guest's ID matches the room they’re accessing — anyone with a spare key can wander into the penthouse! 🏨 With this vulnerability, an attacker who already has system-level privileges could write data outside the intended boundaries, potentially gaining control over crucial system functions. It’s like letting someone in the penthouse rearrange the entire hotel — chaos can ensue!
