CVE-2026-68087

Description

A flaw was found in the Linux kernel. Specifically, the Wacom Human Interface Device (HID) driver uses an incorrect memory allocation flag (GFP_KERNEL) within a critical section of code that operates in an atomic context. This can cause the system to attempt to sleep, leading to a "scheduling while atomic" bug. This vulnerability could result in system instability or a denial of service.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
