| 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
The Linux kernel contains a flaw in the networking subsystem related to the hns3 driver. Specifically, the system lacks proper validation of VLAN IDs received from a Virtual Function (VF) configuration mailbox. This can lead to an out-of-bounds memory access if the VLAN ID is greater than or equal to VLAN N VID when used without validation. The
vlan del fail bmap length is determined by BITS TO LONGS(VLAN N VID), and an invalid VLAN ID can cause memory corruption.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
