CVE-2024-47676

7.8 · HIGH
Published Oct 21, 2024 linux CWE-416 EPSS 0.24% (15th pctl)

Overview

CVE-2024-47676 is a high-severity vulnerability affecting linux linux_kernel. It was published on October 21, 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:

mm/hugetlb.c: fix UAF of vma in hugetlb fault pathway

Syzbot reports a UAF in hugetlb_fault(). This happens because

vmf_anon_prepare() could drop the per-VMA lock and allow the current VMA

to be freed before hugetlb_vma_unlock_read() is called.

We can fix this by using a modified version of vmf_anon_prepare() that

doesn't release the VMA lock on failure, and then release it ourselves

after hugetlb_vma_unlock_read().

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.
