This vulnerability involves a use-after-free condition in the Wi-Fi packet processing of Apple iOS and iPadOS devices. An attacker positioned on the same network with elevated privileges could exploit this flaw by sending specially crafted Wi-Fi packets, triggering a denial-of-service condition. Apple has fixed this issue through improved memory management in iOS 18.7.9, iPadOS 18.7.9, and corresponding updates for macOS, tvOS, and watchOS. The CVSS score of 5.3 reflects a medium severity, with attack vector requiring adjacent network access and high attack complexity.

Successful exploitation results in denial-of-service, causing affected devices to become unresponsive or crash. There is no indication of confidentiality or integrity impact. The attack requires the attacker to be in a privileged network position, limiting the attack surface. No known exploits have been reported in the wild.

This vulnerability is fixed in iOS 18.7.9 and iPadOS 18.7.9, as well as in updates for other Apple operating systems. Users and administrators should apply these official updates to remediate the issue. Since the vendor advisory confirms the fix, no additional mitigation steps are required beyond patching.
