CVE-2025-43424

Process crash via malformed HID input

Published Nov 4, 2025 · Updated Nov 4, 2025

Bounds-checking failure in Multi-Touch in Apple iOS and iPadOS before 26.1 allows physically proximate attackers to crash a process via HID input. The Multi-Touch component performs inadequate bounds checks while handling input from an HID device, allowing crafted device data to reach an invalid range and terminate the process. Exploitation requires a malicious HID device within direct device range; the reported consequence is a process crash, with no published data-access or code-execution impact.
