CVE-2008-3525

Published: 03 September 2008

The sbni_ioctl function in drivers/net/wan/sbni.c in the wan subsystem in the Linux kernel 2.6.26.3 does not check for the CAP_NET_ADMIN capability before processing a (1) SIOCDEVRESINSTATS, (2) SIOCDEVSHWSTATE, (3) SIOCDEVENSLAVE, or (4) SIOCDEVEMANSIPATE ioctl request, which allows local users to bypass intended capability restrictions.

From the Ubuntu security team

It was discovered that the SBNI WAN driver did not correctly check for the NET_ADMIN capability. A malicious local root user lacking CAP_NET_ADMIN would be able to change the WAN device configuration, leading to a denial of service.
