Linux kernel (affected versions not specified)
Description
A NULL pointer dereference issue exists in the
ice unplug aux dev() function when a reset is issued on a driver loaded without RDMA support. This can lead to a kernel crash. The issue occurs when attempting to remove RDMA's non-existent auxbus device via the /sys/class/net/<if>/device/reset endpoint. Specifically, the ice unplug aux dev() function does not adequately check for NULL pointers, leading to a dereference.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
