Detailed vulnerability description
The vulnerability allows an adjacent attacker to cause DoS condition on the target system.
The weakness exists in the virtnet_probe function in drivers/net/virtio_net.c due to attempts to support a FRAGLIST feature without proper memory allocation. An adjacent attacker can submit a specially crafted sequence of fragmented packets, trigger buffer overflow and cause the service to crash.
