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

Description An issue exists in the GPIO sysfs implementation where exporting a GPIO over sysfs and subsequently unbinding the parent GPIO controller causes the exported attribute to persist under '/sys/class/gpio'. This occurs because the removal of the parent device prevents the gpiod unexport() function from associating the descriptor with the device, which prevents the final reference from being dropped.

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