CVE-2011-1581

Publication date 26 May 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.

From the Ubuntu Security Team

Phil Oester discovered that the network bonding system did not correctly handle large queues. On some systems, a remote attacker could send specially crafted traffic to crash the system, leading to a denial of service.
