An official patch is available and should be applied to affected Linux kernel versions. Users should update to the fixed kernel releases to remediate this vulnerability. No additional mitigation steps are indicated by the vendor advisory.
Description
A vulnerability in the Linux kernel's octeontx2-af driver related to incorrect validation of the NIX maximum number of LFs (logical functions) has been resolved. The issue involved an incorrect condition used to check whether any LFs were assigned before setting the maximum number of LFs via a devlink command. This flaw could potentially allow improper configuration of LFs. A patch correcting this validation logic is available.
