Description

Linux Kernel contains a flaw that may allow a remote denial of service. The issue is triggered when the 'igb_receive_skb 'function in 'drivers/net/igb/igb_main.c' in the Intel Gigabit Ethernet subsystem has SR-IOV and promiscuous mode enabled without any VLANs registered. This may allow a remote attacker to cause a NULL pointer dereference and panic denial of service via a VLAN tagged frame.
