CVE-2015-5156
CVSS V2 Medium 6.1
CVSS V3 None
Description
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.

An attacker on the local network could potentially use this flaw to crash the system, or, although unlikely, elevate their privileges on the system. | Description | updated |
