CVSS v3.1
6.3
Medium
| Vector | AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the i40e driver in the Linux kernel, where an untrusted Virtual Function (VF) can remove a Media Access Control (MAC) address that was set administratively by the Physical Function (PF). This occurs when the VF is put down and attempts to delete all MACs, resulting in the removal of the MAC from MAC filters and the zeroing of the primary VF MAC. The vulnerability can be reproduced by creating a VF, setting the VF interface up, administratively setting the VF's MAC, and then putting the VF interface down.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
