CVE-2023-53797
Published Dec 9, 2025
Modified Apr 15, 2026
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.

Frequently Asked Questions
What is CVE-2023-53797? +
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.
How do I check if I'm vulnerable to CVE-2023-53797? +
