  "description": "In the Linux kernel, the following vulnerability has been resolved:  nbd: Fix hung when signal interrupts nbd_start_device_ioctl()  syzbot reported hung task [1].  The following program is a simplified version of the reproducer:  int main(void) { \tint sv[2], fd;  \tif (socketpair(AF_UNIX, SOCK_STREAM, 0, sv) \u003C 0) \t\treturn 1; \tif ((fd = open(\u0022/dev/nbd0\u0022, 0)) \u003C 0) \t\treturn 1; \tif (ioctl(fd, NBD_SET_SIZE_BLOCKS, 0x81) \u003C 0) \t\treturn 1; \tif (ioctl(fd, NBD_SET_SOCK, sv[0]) \u003C 0) \t\treturn 1; \tif (ioctl(fd, NBD_DO_IT) \u003C 0) \t\treturn 1; \treturn 0; }  When signal interrupt nbd_start_device_ioctl() waiting the condition atomic_read(\u0026config-\u003Erecv_threads) == 0, the task can hung because it waits the completion of the inflight IOs.  This patch fixes the issue by clearing queue, not just shutdown, when signal interrupt nbd_start_device_ioctl().",
