Overview

CVE-2024-38568 is a high-severity vulnerability. It was published on June 19, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

drivers/perf: hisi: hns3: Fix out-of-bound access when valid event group

The perf tool allows users to create event groups through following

cmd [1], but the driver does not check whether the array index is out

of bounds when writing data to the event_group array. If the number of

events in an event_group is greater than HNS3_PMU_MAX_HW_EVENTS, the

memory write overflow of event_group array occurs.

Add array index check to fix the possible array out of bounds violation,

and return directly when write new events are written to array bounds.

There are 9 different events in an event_group.

[1] perf stat -e '{pmu/event1/, ... ,pmu/event9/}

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.
