## Technical details

This is a use-after-free vulnerability in the Windows Overlay Filter driver, a kernel-mode component responsible for managing graphical overlays in Windows. The vulnerability arises from improper memory lifecycle management that allows freed memory to be accessed, potentially leading to information disclosure. Attack precondition requires the attacker to already be authorized with network access; the vulnerability does not enable privilege escalation but can leak sensitive kernel or application memory contents over the network. Microsoft has released a security patch to address the issue.
