Overview

CVE-2024-46770 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 18, 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:

ice: Add netif_device_attach/detach into PF reset flow

Ethtool callbacks can be executed while reset is in progress and try to

access deleted resources, e.g. getting coalesce settings can result in a

NULL pointer dereference seen below.

Reproduction steps:

Once the driver is fully initialized, trigger reset:

# echo 1 > /sys/class/net/<interface>/device/reset

when reset is in progress try to get coalesce settings using ethtool:

# ethtool -c <interface>

BUG: kernel NULL pointer dereference, address: 0000000000000020
