  "details": "In the Linux kernel, the following vulnerability has been resolved:  usb: xhci: Fix sleep in atomic context in xhci_free_streams()  When a USB device with active stream endpoints is disconnected, xhci_free_streams() is called from the hub_event workqueue to free the stream resources.  It calls xhci_free_stream_info() while holding xhci-\u003elock with irqs disabled.  xhci_free_stream_info() invokes xhci_free_stream_ctx(), which calls dma_free_coherent() for large stream context arrays.  dma_free_coherent() can sleep (e.g. via vunmap), triggering a BUG when called from atomic context.  Call trace:  dma_free_attrs+0x174/0x220  xhci_free_stream_info+0xd0/0x11c  xhci_free_streams+0x278/0x37c  usb_free_streams+0x98/0xc0  usb_unbind_interface+0x1b8/0x2f8  device_release_driver_internal+0x1d4/0x2cc  device_release_driver+0x18/0x28  bus_remove_device+0x160/0x1a4  device_del+0x1ec/0x350  usb_disable_device+0x98/0x214  usb_disconnect+0xf0/0x35c  hub_event+0xab4/0x19ec  process_one_work+0x278/0x63c  Fix this by saving the stream_info pointers and clearing the ep references under the lock, then calling xhci_free_stream_info() outside the lock where sleeping is allowed.",
