In the Linux kernel, the following vulnerability has been resolved: virtio-pci: Fix result size returned for the admin command completion The result size returned by virtio_pci_admin_dev_parts_get() is 8 bytes larger than the actual result data size. This occurs because the result_sg_size field of the command is filled with the result length from virtqueue_get_buf(), which includes both the data size and an additional 8 bytes of status. This oversized result size causes two issues: 1. The state transferred to the destination includes 8 bytes of extra data at the end. 2. The allocated buffer in
