Description

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.

Affected configurations

• linux linux kernel (< 3.1) • avaya 9608 firmware (>= 6.0 <= 6.6.0) • avaya 9608g firmware (>= 6.0 <= 6.6.0) • avaya 9611g firmware (>= 6.0 <= 6.6.0) • avaya 9621g firmware (>= 6.0 <= 6.6.0) • avaya 9641g firmware (>= 6.0 <= 6.6.0) • avaya 9641gs firmware (>= 6.0 <= 6.6.0)
