Linux Kernel Buffer Oveflow in virtio-net GRO Fragmentation Processing Lets Remote Users Cause the Target System to Crash or Potentially Execute Arbitrary Code
SecurityTracker Alert ID:  1034045
SecurityTracker URL:  http://securitytracker.com/id/1034045
CVE Reference:   CVE-2015-5156   (Links to External Site)
Date:  Nov 3 2015
Impact:   Denial of service via network, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in the Linux kernel. A remote user can cause the target system to crash or potentially execute arbitrary code with elevated privileges.

A remote user on the local network can send specially crafted packet fragments to trigger a buffer overflow in virtio-net and cause the target system to crash or potentially execute arbitrary code with elevated privileges.

Systems with Generic Receive Offload (GRO) enabled in a bridged network configuration are affected.

Jason Wang of Red Hat reported this vulnerability.

Impact:   A remote user can cause the target system to crash or potentially execute arbitrary code with elevated privileges.
Solution:   A proposed patch is available at:
