CVE-2010-4263: Null Pointer Dereference
First published: Mon Dec 06 2010(Updated: )
If igb's SR-IOV and promiscuous mode are enabled and the interface receives a tag VLAN packet, this will result in a null pointer dereference. To fix this, we will backport upstream commit 31b24b95 to ensure that vlan_gro_receive is only used if vlans have been registered to the adapter structure. [ This fixes bugzilla entry 15582 -Eric Dumazet] It matters if CONFIG_PCI_IOV is enabled, e.g. grep -ir SRIOV drivers/net/igb/*.
