CVE-2025-38314 is a vulnerability in the Linux kernel's virtio-pci driver where the result size returned for the admin command completion is incorrectly reported as 8 bytes larger than the actual data. This causes the kernel to transfer extra data and may lead to buffer size mismatches and failures when reading beyond allocated memory. The issue has been fixed by adjusting the reported result size to exclude the extra status bytes. The fix has been tested with live migrations involving virtio-net and virtio-blk devices.
