Overview

CVE-2022-48746 is a medium-severity vulnerability. It was published on June 20, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

net/mlx5e: Fix handling of wrong devices during bond netevent

Current implementation of bond netevent handler only check if

the handled netdev is VF representor and it missing a check if

the VF representor is on the same phys device of the bond handling

the netevent.

Fix by adding the missing check and optimizing the check if

the netdev is VF representor so it will not access uninitialized

private data and crashes.
