A flaw was found in the Linux kernel's Google Virtual NIC (gve) driver. A local user with raw packet access or an adjacent guest system can trigger a Denial of Service (DoS) by sending network packets with an excessively large segment size. The driver fails to validate the Maximum Segment Size (MSS) before writing it to a hardware descriptor during TCP Segmentation Offload (TSO), causing the size value to wrap or truncate to zero. This misconfiguration can cause network packet processing failures and disrupt network connectivity.
kernel: gve: DQO: reject TSO packets with an out of range MSS — rated Moderate by Red Hat. Released 2026-10-18, updated 2026-10-20.
