Vulnerability from github – Published: 2025-12-09 03:31 – Updated: 2026-08-04 12:34

Details

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

7.1 (High)

The int type does not offer\nenough space to store these values, and attempting to use it is a\nrecipe for problems. In this particular case, overflows would occur\nwhen calculating/storing timestamps leading to incorrect values being\nreported to userspace.

This matches the Adjacent classification used for other wacom BT report-handler CVEs.\nAC:L - The truncation is unconditional and deterministic \u2014 a signed int holds only ~2.1 seconds of nanoseconds, so ktime_get() values stored in time_delayed wrap within seconds of uptime on every affected device with no attacker-uncontrollable preconditions.\nPR:N - No credentials or privileges on the target system are needed; the malformed state is produced from data supplied by the Bluetooth HID peer, and wacom_raw_event()/wacom_wac_irq() perform no capability or permission checks before dispatching to wacom_intuos_pro2_bt_pen().\nUI:N - The overflow occurs during ordinary pen-report processing on a connected tablet with no victim action required beyond normal device use.\nS:U - The corrupted timestamps stay within the kernel input subsystem and the evdev consumers of the same system; no security authority or isolation boundary is crossed.\nC:N - The bad values are derived solely from truncated monotonic clock readings, which userspace can already obtain via clock_gettime(); no kernel memory contents, pointers, or heap data are disclosed.\nI:L - The kernel writes incorrect event timestamps into the input event stream delivered to userspace, so applications consume corrupted data; the modification is real but bounded to the timestamp fields of input events.\nA:H - The commit states the bad timestamps cause input handling in userspace to appear hung, i.e. a complete loss of availability of the affected input device \u2014 on graphics workstations, kiosks, and embedded panels where the digitizer is the primary or sole input device this is a total denial of interactive service requiring intervention to recover."

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
