Published: 29 September 2010

Buffer overflow in the niu_get_ethtool_tcam_all function in drivers/net/niu.c in the Linux kernel before 2.6.36-rc4 allows local users to cause a denial of service or possibly have unspecified other impact via the ETHTOOL_GRXCLSRLALL ethtool command.

From the Ubuntu security team

Ben Hutchings discovered that the ethtool interface did not correctly check certain sizes. A local attacker could perform malicious ioctl calls that could crash the system, leading to a denial of service.
