Red Hat Security Advisory 2012-1589-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue: A flaw was found in the way the Linux kernel's dl2k driver, used by certain D-Link Gigabit Ethernet adapters, restricted IOCTLs. A local, unprivileged user could use this flaw to issue potentially harmful IOCTLs, which could cause Ethernet adapters using the dl2k driver to malfunction.
