A flaw was found in the Linux kernel's Alps Human Interface Device (HID) driver. If registration of an input device fails during configuration, the driver frees the device memory while communication channels are already active, leaving a dangling reference. An attacker capable of attaching a malicious device or sending crafted input reports can trigger a use-after-free condition during this failure window. This flaw primarily results in a Denial of Service (DoS) through a kernel crash, and may potentially allow arbitrary code execution.
