Overview

CVE-2024-26784 is a medium-severity vulnerability affecting linux linux_kernel. It was published on April 4, 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:

pmdomain: arm: Fix NULL dereference on scmi_perf_domain removal

On unloading of the scmi_perf_domain module got the below splat, when in

the DT provided to the system under test the '#power-domain-cells' property

was missing. Indeed, this particular setup causes the probe to bail out

early without giving any error, which leads to the ->remove() callback gets

to run too, but without all the expected initialized structures in place.

Add a check and bail out early on remove too.
