  "details": "In the Linux kernel, the following vulnerability has been resolved:  usb: cdns3: gadget: fix state inconsistency on gadget init failure  When cdns3_gadget_start() fails, the DRD hardware is left in gadget mode while software state remains INACTIVE, creating hardware/software state inconsistency.  When switching to host mode via sysfs:   echo host \u003e /sys/class/usb_role/13180000.usb-role-switch/role  The role state is not set to CDNS_ROLE_STATE_ACTIVE due to the error, so cdns_role_stop() skips cleanup because state is still INACTIVE. This violates the DRD controller design specification (Figure22), which requires returning to idle state before switching roles.  This leads to a synchronous external abort in xhci_gen_setup() when setting up the host controller:  [  516.440698] configfs-gadget 13180000.usb: failed to start g1: -19 [  516.442035] cdns-usb3 13180000.usb: Failed to add gadget [  516.443278] cdns-usb3 13180000.usb: set role 2 has failed ...
