Overview

CVE-2024-42107 is a medium-severity vulnerability. It was published on July 30, 2024 and has a CVSS 3.1 base score of 4.7 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.7, 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: Don't process extts if PTP is disabled

The ice_ptp_extts_event() function can race with ice_ptp_release() and

result in a NULL pointer dereference which leads to a kernel panic.

Panic occurs because the ice_ptp_extts_event() function calls

ptp_clock_event() with a NULL pointer. The ice driver has already

released the PTP clock by the time the interrupt for the next external

timestamp event occurs.

To fix this, modify the ice_ptp_extts_event() function to check the

PTP state and bail early if PTP is not ready.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
