Overview

CVE-2024-35878 is a medium-severity vulnerability. It was published on May 19, 2024 and has a CVSS 3.1 base score of 5.3 (MEDIUM).

Technical description

In the Linux kernel, the following vulnerability has been resolved:

of: module: prevent NULL pointer dereference in vsnprintf()

In of_modalias(), we can get passed the str and len parameters which would

cause a kernel oops in vsnprintf() since it only allows passing a NULL ptr

when the length is also 0. Also, we need to filter out the negative values

of the len parameter as these will result in a really huge buffer since

snprintf() takes size_t parameter while ours is ssize_t...

Found by Linux Verification Center (linuxtesting.org) with the Svace static

analysis tool.

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.
