In the Linux kernel, the following vulnerability has been resolved:

USB: gadget: Fix use-after-free during usb config switch

In the process of switching USB config from rndis to other config, if the hardware does not support the ->pullup callback, or the hardware encounters a low probability fault, both of them may cause the ->pullup callback to fail, which will then cause a system panic (use after free).

The gadget drivers sometimes need to be unloaded regardless of the hardware's behavior.

Analysis as follows: ======================================================================= (1) write /config/usb_gadget/g1/UDC "none"

If gadget->ops->pullup() return an error, function rndis_close() will be called, then it will causes a use-after-free problem. =======================================================================
