CVE-2012-2313

Published: 14 May 2012

The rio_ioctl function in drivers/net/ethernet/dlink/dl2k.c in the Linux kernel before 3.3.7 does not restrict access to the SIOCSMIIREG command, which allows local users to write data to an Ethernet adapter via an ioctl call.

From the Ubuntu security team

Stephan Mueller reported a flaw in the Linux kernel's dl2k network driver's handling of ioctls. An unprivileged local user could leverage this flaw to cause a denial of service.
