Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> misc: microchip: pci1xxxx: fix double free in the error handling of gp_aux_bus_probe()<br /> <br /> When auxiliary_device_add() returns error and then calls<br /> auxiliary_device_uninit(), callback function<br /> gp_auxiliary_device_release() calls ida_free() and<br /> kfree(aux_device_wrapper) to free memory. We should&amp;#39;t<br /> call them again in the error handling path.<br /> <br /> Fix this by skipping the redundant cleanup functions.
