CVE-2023-53797 (GCVE-0-2023-53797)

VLAI?
Summary
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.
Severity ?
No CVSS data available.
