Description
In the Linux kernel, the following vulnerability has been resolved: HID: wacom: Use ktime_t rather than int when dealing with timestamps Code which interacts with timestamps needs to use the ktime_t type returned by functions like ktime_get. The int type does not offer enough space to store these values, and attempting to use it is a recipe for problems. In this particular case, overflows would occur when calculating/storing timestamps leading to incorrect values being reported to userspace. In some cases these bad timestamps cause input handling in userspace to appear hung.

Executive Summary

This vulnerability in the Linux kernel involves improper handling of timestamps in the HID wacom driver. The code used an int type to store timestamps, which is insufficient and causes overflows. This leads to incorrect timestamp values being reported to userspace, potentially causing input handling to appear hung.

Impact Analysis

The impact of this vulnerability is that input devices using the affected driver may report incorrect timestamps, which can cause input handling in userspace to appear hung or unresponsive, potentially affecting user experience or device functionality.
