Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel's gpio/mpsse driver. Specifically, when an interrupt request (IRQ) worker is active, disconnecting the device can lead to a system crash. This issue stemmed from the driver being initially designed for hardware not intended for hotplugging, leading to the lack of proper handling for device disconnections during worker execution. The resolution involves utilizing a spinlock to safeguard a list of workers and ensure they are properly terminated upon disconnection.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
