## Technical details

A double free vulnerability exists in the Microsoft Windows Search Component, where memory is incorrectly freed more than once during processing. This memory corruption flaw can be triggered by an authenticated attacker over the network to corrupt heap memory and achieve arbitrary code execution with elevated privileges. The vulnerability requires prior authentication and network reachability to the affected system. An attacker exploiting this issue could escalate privileges and gain control over the compromised system. Microsoft has released security patches to address this vulnerability.
