  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nserial: max3100: Lock port->lock when calling uart_handle_cts_change()\n\nuart_handle_cts_change() has to be called with port lock taken,\nSince we run it in a separate work, the lock may not be taken at\nthe time of running. Make sure that it's taken by explicitly doing\nthat. Without it we got a splat:\n\n  WARNING: CPU: 0 PID: 10 at drivers/tty/serial/serial_core.c:3491 uart_handle_cts_change+0xa6/0xb0\n  ...\n  Workqueue: max3100-0 max3100_work [max3100]\n  RIP: 0010:uart_handle_cts_change+0xa6/0xb0\n  ...\n   max3100_handlerx+0xc5/0x110 [max3100]\n   max3100_work+0x12a/0x340 [max3100]",
