| Vadim Rozenfeld | 2015-11-05 01:15:37 UTC | Doc Text | Cause: Windows virtio-blk device driver doesn't perform LBA sanity check before submitting request to QEMU Consequence: Some applications can issue out-of-bounds read/write requests which cause QEMU o trigger this situation. Fix: Check LBA before submitting request to QEMU and fail anyone which is not in the range. Result: virtio-blk driver declines any out-of-bound requests. |

| Doc Text | Cause: Windows virtio-blk device driver doesn't perform LBA sanity check before submitting request to QEMU Consequence: Some applications can issue out-of-bounds read/write requests which cause QEMU o trigger this situation. Fix: Check LBA before submitting request to QEMU and fail anyone which is not in the range. Result: virtio-blk driver declines any out-of-bound requests. | Previously, Windows guests in some cases issued out-of-bounds read and write requests to a virtio device, which caused the guest to become unresponsive. Now, the Windows virtio-blk device drive performs logical block addressing (LBA) sanity checks before submitting requests to QEMU, and does not submit requests that are out-of-bounds. As a result, the described problem no longer occurs. |
