CVE-2026-98859

A flaw was found in the Linux kernel's Human Interface Device HID multitouch driver. When a multitouch device is disconnected or removed, the driver fails to prevent the release timer from being rescheduled by incoming input reports. Once the driver deallocates the device data, the timer callback...

CVE-2026-98859

The Linux kernel contains a vulnerability in the HID multitouch subsystem where the mt_remove() function fails to properly prevent the sticky-finger timer from being rearmed during hardware removal. While timer_delete_sync() is used to quiesce the timer, it does not prevent the transport layer fr...
