CVE-2011-4112
Published: 17 May 2012
The net subsystem in the Linux kernel before 3.1 does not properly restrict use of the IFF_TX_SKB_SHARING flag, which allows local users to cause a denial of service (panic) by leveraging the CAP_NET_ADMIN capability to access /proc/net/pktgen/pgctrl, and then using the pktgen package in conjunction with a bridge device for a VLAN interface.
