Vulnerability from fkie_nvd - Published: 2024-05-21 16:15 - Updated: 2025-09-26 16:18
Severity ?
Summary
In the Linux kernel, the following vulnerability has been resolved:
hid: cp2112: Fix duplicate workqueue initialization
Previously the cp2112 driver called INIT_DELAYED_WORK within
cp2112_gpio_irq_startup, resulting in duplicate initilizations of the
workqueue on subsequent IRQ startups following an initial request. This
resulted in a warning in set_work_data in workqueue.c, as well as a rare
NULL dereference within process_one_work in workqueue.c.
Initialize the workqueue within _probe instead.
