In the Linux kernel, the following vulnerability has been resolved: bus: mhi: ep: Fix device refcount leak in the error path of MHI device creation mhi_ep_create_device() takes one device reference for the UL channel and another for the DL channel after allocating the transfer device. These references are normally released by mhi_ep_destroy_device() before the device itself is removed. If dev_set_name() or device_add() fails, the error path currently drops only one reference. The remaining channel references keep the device from being released and leave the channels associated with a device that was never registered. Route both failures through a common unwind path that drops the DL channel reference, the UL channel reference, and the initial reference from device_initialize().
