Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: usb: musb: sunxi: Fix accessing an released usb phy Commit 6ed05c68cbca ("usb: musb: sunxi: Explicitly release USB PHY on exit") will cause that usb phy @glue->xceiv is accessed after released. 1) register platform driver @sunxi_musb_driver // get the usb phy @glue->xceiv sunxi_musb_probe() -> devm_usb_get_phy(). 2) register and unregister platform driver @musb_driver musb_probe() -> sunxi_musb_init() use the phy here //the phy is released here musb_remove() -> sunxi_musb_exit() -> devm_usb_put_phy() 3) register @musb_driver again musb_probe() -> sunxi_musb_init() use the phy here but the phy has been released at 2). ... Fixed by reverting the commit, namely, removing devm_usb_put_phy() from sunxi_musb_exit().
