| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An issue exists in the Linux kernel related to the nixgbe driver, specifically concerning the incorrect mapping used in EEE (Energy Efficient Ethernet) link mode. The driver incorrectly utilized
ixgbe lp map when it should have used ixgbe ls map for populating supported and advertised link mode bitmaps. This resulted in incorrect bit settings and a potential out-of-bounds access due to the differing sizes and purposes of these maps. The fix involves using ixgbe ls map for supported and advertised link modes, reserving ixgbe lp map for link partner mapping.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
