"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: core: clear both ep_in and ep_out for non-ep0 control endpoints\n\nIn usb_enable_endpoint(), non-zero control endpoints (where\nusb_endpoint_xfer_control(&ep->desc) is true) populate both\ndev->ep_in[epnum] and dev->ep_out[epnum] with the same struct\nusb_host_endpoint pointer.\n\nHowever, usb_disable_endpoint() only clears either dev->ep_out[epnum] or\ndev->ep_in[epnum] depending on the direction bit of epaddr when\nreset_hardware is set, leaving the opposite direction's array slot\npointing to the disabled/freed endpoint.\n\nClear both dev->ep_out[epnum] and dev->ep_in[epnum] when disabling a\nnon-ep0 control endpoint with reset_hardware set, and update the\nfunction kerneldoc accordingly.\n\nTested in QEMU against Linux 7.3.0-rc3 using dummy_hcd and raw-gadget to\nenumerate a USB device with a non-zero control endpoint\n(bEndpointAddress 0x01, bmAttributes USB_ENDPOINT_XFER_CONTROL),\nverifying that both dev->ep_in[1] and dev->ep_out[1] are cleared when\nthe interface is disabled."
