Executive brief
A memory handling vulnerability in Apple operating systems could allow an attacker on the same local network to crash a device. This affects a wide range of Apple products including iPhones, iPads, Macs, and Apple Watches. Successful exploitation results in a denial-of-service, temporarily disrupting the use of the device and its services.
Technical details
A denial-of-service vulnerability exists across multiple Apple operating systems due to improper memory handling. An attacker positioned on the same local network (adjacent) can exploit this flaw to trigger a system crash or service disruption. The issue was addressed by Apple through improved memory management logic. Affected platforms include iOS, iPadOS, macOS (Sonoma, Sequoia, and Tahoe), tvOS, visionOS, and watchOS. Patches are available in the latest software updates for each respective platform.
