The igb_receive_skb function in drivers/net/igb/igb_main.c in the Intel Gigabit Ethernet (aka igb) subsystem in the Linux kernel before 2.6.34, when Single Root I/O Virtualization (SR-IOV) and promiscuous mode are enabled but no VLANs are registered, allows remote attackers to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact via a VLAN tagged frame.

Security readout for executives and security teams

This is a Linux kernel network-driver crash issue. Systems using Intel igb with SR-IOV and promiscuous mode enabled, and no VLANs registered, could panic when receiving a VLAN-tagged frame. Business impact is availability loss on affected hosts, especially legacy virtualization or network-facing environments. Exposure is likely limited to legacy Linux kernels, vendor appliances, or hypervisor distributions using the Intel Gigabit Ethernet igb driver with SR-IOV and promiscuous mode enabled. Prioritize legacy virtualization and network infrastructure first. This is not evidenced as actively exploited, but a remote crash of host networking can create business interruption if affected configurations remain in production. Mitigation focus: Upgrade affected Linux kernels or vendor builds to fixed releases, including kernel 2.6.34 or later where applicable.; Apply relevant Red Hat or VMware advisories if using those supported platforms.; Review vendor guidance for backported fixes in maintained distributions..
