The bond_select_queue function in drivers/net/bonding/bond_main.c in the Linux kernel before 2.6.39, when a network device with a large number of receive queues is installed but the default tx_queues setting is used, does not properly restrict queue indexes, which allows remote attackers to cause a denial of service (BUG and system crash) or possibly have unspecified other impact by sending network traffic.

Security readout for executives and security teams

CVE-2011-1581 is a Linux kernel bonding-driver flaw that can let remote network traffic crash affected systems. Business risk is mainly service outage, not confirmed data theft. Exposure depends on old kernels before 2.6.39 and specific network queue conditions. Likely exposure is limited to systems running Linux kernels before 2.6.39 with bonding enabled and network devices presenting many receive queues while default tx_queues is used. Modern supported distributions are likely patched, but legacy appliances or embedded Linux builds need verification. Treat this as a targeted legacy-infrastructure availability risk. It should not displace actively exploited vulnerabilities, but critical networked systems still running old kernels should be checked because a crash can interrupt business services. Mitigation focus: Upgrade to a vendor-supported kernel containing the bonding queue-index fix.; Confirm distribution backports if kernel version remains below 2.6.39.; Review legacy appliances and embedded Linux systems for vulnerable bonding driver builds..
