HIGHCVSS 3.0
EPSS 6.39%
Description
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.

Remediation
Red Hat statement
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.
