Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ixgbe: fix incorrect map used in eee linkmode<br /> <br /> incorrectly used ixgbe_lp_map in loops intended to populate the<br /> supported and advertised EEE linkmode bitmaps based on ixgbe_ls_map.<br /> This results in incorrect bit setting and potential out-of-bounds<br /> access, since ixgbe_lp_map and ixgbe_ls_map have different sizes<br /> and purposes.<br /> <br /> ixgbe_lp_map[i] -&gt; ixgbe_ls_map[i]<br /> <br /> Use ixgbe_ls_map for supported and advertised linkmodes, and keep<br /> ixgbe_lp_map usage only for link partner (lp_advertised) mapping.
