CVE-2026-68087
Overview
CVE-2026-68087 is a known-severity vulnerability. It was published on August 10, 2026.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
HID: wacom: use GFP_ATOMIC in wacom_wac_queue_flush()
wacom_wac_queue_flush() is called via the .raw_event callback
(wacom_raw_event → wacom_wac_pen_serial_enforce → wacom_wac_queue_flush).
For USB HID devices, this callback is invoked from hid_irq_in(), which
is a URB completion handler running in atomic context. Using GFP_KERNEL
in this path can sleep, leading to a "scheduling while atomic" bug.
Use GFP_ATOMIC instead. The existing code already handles allocation
failure by skipping the fifo entry and continuing.
