      "title": "vsock/virtio: flush works in dependency order",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nvsock/virtio: flush works in dependency order\n\nvirtio_vsock_remove() stops the virtqueues and then flushes each work\nitem before freeing the enclosing virtio_vsock.  The current order does\nnot account for dependencies between those items: tx_work may queue\nsend_pkt_work, and send_pkt_work may queue rx_work.\n\nIn particular, send_pkt_work can set restart_rx and release tx_lock.\nThe remove path can then stop the queues and flush rx_work before\nsend_pkt_work queues it.  Although the later send_pkt_work flush waits\nfor that producer to finish, nothing waits for the newly queued rx_work,\nso kfree(vsock) can race with it.\n\nKASAN reported:\n\n  BUG: KASAN: slab-use-after-free in\n  virtio_transport_rx_work+0x487/0x4b0\n  Read of size 8 at addr ffff888114c2b008 by task kworker/1:1/47\n  Workqueue: virtio_vsock virtio_transport_rx_work\n  Call Trace:\n   virtio_transport_rx_work+0x487/0x4b0\n   process_one_work+0x688/0x1120\n   worker_thread+0x45b/0xd10\n  Allocated by task 1:\n   virtio_vsock_probe+0xef/0x6b0\n  Freed by task 84:\n   kfree+0x131/0x3c0\n   virtio_vsock_remove+0xd1/0x100\n\nFlush the works in producer-to-consumer order.  virtio_vsock_vqs_del()\nhas already disabled the queue callbacks and cleared the run flags, so\nafter tx_work and send_pkt_work are drained, no source remains that can\nqueue rx_work after its flush.",
