Descriptions

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.

La función atl2_probe en drivers/net/ethernet/atheros/atlx/atl2.c en el kernel de Linux hasta la versión 4.5.2 activa incorrectamente scatter/gather I/O, lo que permite a atacantes remotos obtener información sensible de la memoria del kernel leyendo datos de paquete.

It was discovered that the atl2_probe() function in the Atheros L2 Ethernet driver in the Linux kernel incorrectly enabled scatter/gather I/O. A remote attacker could use this flaw to obtain potentially sensitive information from the kernel memory.
