      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: udc: Fix use-after-free in gadget_match_driver\n\nThe udc structure acts as the management structure for the gadget,\nbut their lifecycles are decoupled. A race condition exists where\nusb_del_gadget() frees the udc memory (e.g., via mode-switch work)\nwhile gadget_match_driver() concurrently accesses the freed udc memory\n(e.g., via configfs), causing a Use-After-Free (UAF) that triggers a\nNULL pointer dereference when the freed memory is zeroed:\n\n[39430.908615][ T1171] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000\n[39430.911397][ T1171] pc : __pi_strcmp+0x20/0x140\n[39430.911441][ T1171] lr : gadget_match_driver+0x34/0x60\n...\n[39430.911890][ T1171]  usb_gadget_register_driver_owner+0x50/0xf8\n[39430.911910][ T1171]  gadget_dev_desc_UDC_store+0xf4/0x140\n[39430.931308][ T1171]  configfs_write_iter+0xec/0x134\n\n[39430.957058][ T1171] Workqueue: events_freezable __dwc3_set_mode\n[39430.957287][ T1171]  dwc3_gadget_exit+0x34/0x8c\n[39430.957304][ T1171]  __dwc3_set_mode+0xc0/0x664\n\nFix this by ensuring the udc structure remains allocated until the\ngadget is released. To achieve this, introduce a new\nusb_gadget_release() routine to the core. When the gadget is added,\nusb_add_gadget() stores the gadget's release routine in the udc\nstructure and takes a reference to the udc. When the gadget is\nreleased, usb_gadget_release() drops the reference to the udc and\nthen calls the gadget's release routine.",
