CVE-2016-2117
The atl2_probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel through 4.5.2 incorrectly enables scatter/gather I/O, which allows remote attackers to obtain sensitive information from kernel memory by reading packet data.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.39%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
