CVE-2026-68087

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.

This vulnerability is rated as Low severity because exploitation requires local access and the presence of specialized Wacom hardware or an emulated USB device. In typical Red Hat Enterprise Linux server deployments, graphics tablet peripherals are not connected, significantly limiting exposure under default configurations. The flaw is confined to causing a kernel crash or system hang without compromising data confidentiality or system integrity.
