CVE-2016-2117
Published: 02 May 2016
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.
From the Ubuntu security team
Justin Yackoski discovered that the Atheros L2 Ethernet Driver in the Linux kernel incorrectly enables scatter/gather I/O. A remote attacker could use this to obtain potentially sensitive information from kernel memory.
