kernel is vulnerable to denial of service. A buffer overflow flaw was found in the way the Linux kernel’s virtio-net subsystem handled certain fraglists when the GRO (Generic Receive Offload) functionality was enabled in a bridged network configuration. An attacker on the local network could potentially use this flaw to crash the system, or, although unlikely, elevate their privileges on the system.
