Published 2024-07-30 · Updated 2024-12-19 · CVE-2024-42116

Positive Technologies (AI Summary)

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.43

Description The issue is related to the igc driver in the Linux kernel, where the igc ptp init() function is called before register netdev(), resulting in a log entry using an uninitialized netdev. This causes the netdev info() call to work on a partially uninitialized netdev. The problem is fixed by calling igc ptp init() after register netdev(), right after the media autosense check.

Recommendations Update to Linux kernel version 6.6.43 or later to resolve the issue. As a temporary workaround, consider modifying the igc driver to call igc ptp init() after register netdev() to prevent the log entry from using an uninitialized netdev.
