Overview

CVE-2024-36000 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 20, 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:

mm/hugetlb: fix missing hugetlb_lock for resv uncharge

There is a recent report on UFFDIO_COPY over hugetlb:

https://lore.kernel.org/all/[email protected]/

350: lockdep_assert_held(&hugetlb_lock);

Should be an issue in hugetlb but triggered in an userfault context, where

it goes into the unlikely path where two threads modifying the resv map

together. Mike has a fix in that path for resv uncharge but it looks like

the locking criteria was overlooked: hugetlb_cgroup_uncharge_folio_rsvd()

will update the cgroup pointer, so it requires to be called with the lock

held.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
