Description Eugene Teo (Security Response) 2010-12-06 01:58:55 UTC
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/*.

Comment 4 Eugene Teo (Security Response) 2010-12-06 02:45:11 UTC
Statement:

This issue did not affect the versions of the Linux kernel as shipped with Red Hat Enterprise Linux 4 and Red Hat Enterprise MRG as they did not include support for PCI I/O Virtualization (IOV). Future updates in Red Hat Enterprise Linux 5 and 6 may address this flaw.
