      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: xhci: Fix sleep in atomic context in xhci_free_streams()\n\nWhen a USB device with active stream endpoints is disconnected,\nxhci_free_streams() is called from the hub_event workqueue to\nfree the stream resources.  It calls xhci_free_stream_info()\nwhile holding xhci->lock with irqs disabled.\n\nxhci_free_stream_info() invokes xhci_free_stream_ctx(), which\ncalls dma_free_coherent() for large stream context arrays.\n\ndma_free_coherent() can sleep (e.g. via vunmap), triggering\na BUG when called from atomic context.\n\nCall trace:\n dma_free_attrs+0x174/0x220\n xhci_free_stream_info+0xd0/0x11c\n xhci_free_streams+0x278/0x37c\n usb_free_streams+0x98/0xc0\n usb_unbind_interface+0x1b8/0x2f8\n device_release_driver_internal+0x1d4/0x2cc\n device_release_driver+0x18/0x28\n bus_remove_device+0x160/0x1a4\n device_del+0x1ec/0x350\n usb_disable_device+0x98/0x214\n usb_disconnect+0xf0/0x35c\n hub_event+0xab4/0x19ec\n process_one_work+0x278/0x63c\n\nFix this by saving the stream_info pointers and clearing the\nep references under the lock, then calling xhci_free_stream_info()\noutside the lock where sleeping is allowed.",
