NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-trace package and not the kernel-rt-trace package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The virtnet_probe function in drivers/net/virtio_net.c in the Linux kernel before 4.2 attempts to support a FRAGLIST feature without proper memory allocation, which allows guest OS users to cause a denial of service (buffer overflow and memory corruption) via a crafted sequence of fragmented packets.
