Vulnerability from cnvd - Published: 2024-03-27

Title

Linux kernel代码问题漏洞（CNVD-2024-14763）

Description

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在代码问题漏洞，该漏洞源于在nft_byteorder_eval()函数中，代码迭代循环并写入dst[0]、dst[1]、dst[2]等，每次迭代都会写入8个字节，但dst[]是一个u32数组，因此每个元素只有4个字节的空间，这意味着每次迭代都会覆盖前一个元素的一部分。攻击者可利用该漏洞造成拒绝服务或可能破坏NetFilter功能。

CVE-2024-0607 (GCVE-0-2024-0607)

Vulnerability from cvelistv5 – Published: 2024-01-18 15:41 – Updated: 2025-11-20 18:09

Title

Kernel: nf_tables: pointer math issue in nft_byteorder_eval()

Summary

A flaw was found in the Netfilter subsystem in the Linux kernel. The issue is in the nft_byteorder_eval() function, where the code iterates through a loop and writes to the `dst` array. On each iteration, 8 bytes are written, but `dst` is an array of u32, so each element only has space for 4 bytes. That means every iteration overwrites part of the previous element corrupting this array of u32. This flaw allows a local user to cause a denial of service or potentially break NetFilter functionality.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
