"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: u_ether: Fix race between gether_disconnect and eth_stop\n\nA race condition between gether_disconnect() and eth_stop() leads to a\nNULL pointer dereference. Specifically, if eth_stop() is triggered\nconcurrently while gether_disconnect() is tearing down the endpoints,\neth_stop() attempts to access the cleared endpoint descriptor, causing\nthe following NPE:\n\n Unable to handle kernel NULL pointer dereference\n Call trace:\n __dwc3_gadget_ep_enable+0x60/0x788\n dwc3_gadget_ep_enable+0x70/0xe4\n usb_ep_enable+0x60/0x15c\n eth_stop+0xb8/0x108\n\nBecause eth_stop() crashes while holding the dev->lock, the thread\nrunning gether_disconnect() fails to acquire the same lock and spins\nforever, resulting in a hardlockup:\n\n Core - Debugging Information for Hardlockup core(7)\n Call trace:\n queued_spin_lock_slowpath+0x94/0x488\n _raw_spin_lock+0x64/0x6c\n gether_disconnect+0x19c/0x1e8\n ncm_set_alt+0x68/0x1a0\n composite_setup+0x6a0/0xc50\n\nThe root cause is that the clearing of dev->port_usb in\ngether_disconnect() is delayed until the end of the function.\n\nMove the clearing of dev->port_usb to the very beginning of\ngether_disconnect() while holding dev->lock. This cuts off the link\nimmediately, ensuring eth_stop() will see dev->port_usb as NULL and\nsafely bail out."
