Published Aug 17, 2024 linux CWE-476 EPSS 0.23% (13th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-43826 is a medium-severity vulnerability affecting linux linux_kernel. It was published on August 17, 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:

nfs: pass explicit offset/count to trace events

nfs_folio_length is unsafe to use without having the folio locked and a

check for a NULL ->f_mapping that protects against truncations and can

lead to kernel crashes. E.g. when running xfstests generic/065 with

all nfs trace points enabled.

Follow the model of the XFS trace points and pass in an explіcit offset

and length. This has the additional benefit that these values can

be more accurate as some of the users touch partial folio ranges.

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.
