Описание
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.
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.
Отчет
This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5 as the code with the flaw is not present in the products listed. This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 6 as the suspected driver does not advertise that it has scatter-gather feature, which presence is essential for the flaw. This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 7 and MRG-2, namely the [atl2] Ethernet driver which is the only driver affected. Future Linux kernel updates for the respective releases might address this issue.
