CVE-2011-3359
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.19%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
