## Technical details

A memory corruption vulnerability exists in the accessory input handling subsystem of iOS and iPadOS due to insufficient input validation. When a maliciously crafted physical accessory communicates with the device, it can trigger an out-of-bounds memory write or similar memory safety violation. The attack requires the attacker to have physical control of a device and connect a malicious accessory, resulting in unexpected process termination (denial of service). The vulnerability has been patched in iOS 27, iPadOS 27, iOS 26.7, and iPadOS 26.7 through improved input validation on accessory data.
