What it is

⚠️ An out-of-bounds read vulnerability in Windows NTFS means a savvy attacker can peek at locally stored information without breaking a sweat! Think of it like a waiter who accidentally hands you someone else’s order from the kitchen instead of yours — you’re not supposed to see that, but it slipped through the cracks! This could lead to the unauthorized disclosure of sensitive information, putting your data confidentiality at risk. An attacker with the right access could exploit this to snoop around and grab things they shouldn’t — like a backstage pass to your personal data.
