Overview

CVE-2024-36020 is a high-severity vulnerability. It was published on May 30, 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:

i40e: fix vf may be used uninitialized in this function warning

To fix the regression introduced by commit 52424f974bc5, which causes

servers hang in very hard to reproduce conditions with resets races.

Using two sources for the information is the root cause.

In this function before the fix bumping v didn't mean bumping vf

pointer. But the code used this variables interchangeably, so stale vf

could point to different/not intended vf.

Remove redundant "v" variable and iterate via single VF pointer across

whole function instead to guarantee VF pointer validity.

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.
