What it is

⚠️ A sneaky out-of-bounds write could empower local attackers! If they've already scored system privileges, they might exploit this flaw without breaking a sweat! 🔥 Think of it like a construction worker who finds a hidden tool in a worksite, allowing them to bypass safety checks. With the right access, they can do quite a bit of damage without anyone noticing! This vulnerability could allow a malicious actor to escalate their privileges and perform actions they shouldn’t have permission for—think unauthorized access to sensitive data or system controls. It’s a real nightmare scenario for system security!
