| Description: | The dma_rx function in drivers/net/wireless/b43/dma.c in the Linux kernel before 2.6.39 does not properly allocate receive buffers, which allows remote attackers to cause a denial of service (system crash) via a crafted frame. A flaw was found in the b43 driver in the Linux kernel. An attacker could use this flaw to cause a denial of service if the system has an active wireless interface using the b43 driver.
