What it is

⚠️ A misstep in page transfer could let guest OS users extend their reach beyond the guest realm! Picture this: they might just open the door to privileged access on the host OS. 🔥 Think of it like a hotel where the cleaning staff find a way into the penthouse suite through a poorly secured service elevator. They’re not supposed to be up there, but a sneaky backdoor gives them unprecedented access! If exploited, a guest OS user could gain privileged access to the host OS, potentially compromising the entire system. This means they could manipulate critical resources, disrupt services, or even sneakily install malicious software. It’s a sneaky little breach that could lead to devastating consequences!
