Title

Linux kernel存在未明漏洞（CNVD-2024-35104）

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存在安全漏洞，该漏洞源于powerpc/pseries模块中在使用kexec时，pseries平台在其他CPU关闭之前禁用了AIL，这可能导致在禁用AIL后执行scv指令的CPU中断，从而在意外的位置触发中断并导致内核崩溃。目前没有详细的漏洞细节提供。

CVE-2024-42230 (GCVE-0-2024-42230)

Vulnerability from cvelistv5 – Published: 2024-07-30 07:47 – Updated: 2026-05-11 20:28

Title

powerpc/pseries: Fix scv instruction crash with kexec

Summary

In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: Fix scv instruction crash with kexec kexec on pseries disables AIL (reloc_on_exc), required for scv instruction support, before other CPUs have been shut down. This means they can execute scv instructions after AIL is disabled, which causes an interrupt at an unexpected entry location that crashes the kernel. Change the kexec sequence to disable AIL after other CPUs have been brought down. As a refresher, the real-mode scv interrupt vector is 0x17000, and the fixed-location head code probably couldn't easily deal with implementing such high addresses so it was just decided not to support that interrupt at all.

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.
