CVE-2024-57947

9.8 · CRITICAL
Published Jan 23, 2025 linux CWE-401 EPSS 0.44% (37th pctl)

Overview

CVE-2024-57947 is a critical-severity vulnerability affecting linux linux_kernel. It was published on January 23, 2025 and has a CVSS 3.1 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

netfilter: nf_set_pipapo: fix initial map fill

The initial buffer has to be inited to all-ones, but it must restrict

it to the size of the first field, not the total field size.

After each round in the map search step, the result and the fill map

are swapped, so if we have a set where f->bsize of the first element

is smaller than m->bsize_max, those one-bits are leaked into future

rounds result map.

This makes pipapo find an incorrect matching results for sets where

first field size is not the largest.

Followup patch adds a test case to nft_concat_range.sh selftest script.

Thanks to Stefano Brivio for pointing out that we need to zero out

the remainder explicitly, only correcting memset() argument isn't enough.

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.
