CVE-2024-26835

5.5 · MEDIUM
Published Apr 17, 2024 linux EPSS 0.23% (13th pctl)

Overview

CVE-2024-26835 is a medium-severity vulnerability affecting linux linux_kernel. It was published on April 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:

netfilter: nf_tables: set dormant flag on hook register failure

We need to set the dormant flag again if we fail to register

the hooks.

During memory pressure hook registration can fail and we end up

with a table marked as active but no registered hooks.

On table/base chain deletion, nf_tables will attempt to unregister

the hook again which yields a warn splat from the nftables core.

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.
