Published Jan 21, 2025 linux CWE-835 EPSS 0.22% (13th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-57940 is a medium-severity vulnerability affecting linux linux_kernel. It was published on January 21, 2025 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:

exfat: fix the infinite loop in exfat_readdir()

If the file system is corrupted so that a cluster is linked to

itself in the cluster chain, and there is an unused directory

entry in the cluster, 'dentry' will not be incremented, causing

condition 'dentry < max_dentries' unable to prevent an infinite

loop.

This infinite loop causes s_lock not to be released, and other

tasks will hang, such as exfat_sync_fs().

This commit stops traversing the cluster chain when there is unused

directory entry in the cluster to avoid this infinite loop.

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.
