Vulnerability from fkie_nvd - Published: 2024-07-29 14:15 - Updated: 2026-06-17 07:47

Severity

5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: s390/mm: Fix VM_FAULT_HWPOISON handling in do_exception() There is no support for HWPOISON, MEMORY_FAILURE, or ARCH_HAS_COPY_MC on s390. Therefore we do not expect to see VM_FAULT_HWPOISON in do_exception(). However, since commit af19487f00f3 ("mm: make PTE_MARKER_SWAPIN_ERROR more general"), it is possible to see VM_FAULT_HWPOISON in combination with PTE_MARKER_POISONED, even on architectures that do not support HWPOISON otherwise. In this case, we will end up on the BUG() in do_exception(). Fix this by treating VM_FAULT_HWPOISON the same as VM_FAULT_SIGBUS, similar to x86 when MEMORY_FAILURE is not configured. Also print unexpected fault flags, for easier debugging. Note that VM_FAULT_HWPOISON_LARGE is not expected, because s390 cannot support swap entries on other levels than PTE level.

Therefore we do not expect to see VM_FAULT_HWPOISON in\ndo_exception().\n\nHowever, since commit af19487f00f3 (\"mm: make PTE_MARKER_SWAPIN_ERROR more\ngeneral\"), it is possible to see VM_FAULT_HWPOISON in combination with\nPTE_MARKER_POISONED, even on architectures that do not support HWPOISON\notherwise. In this case, we will end up on the BUG() in do_exception().\n\nFix this by treating VM_FAULT_HWPOISON the same as VM_FAULT_SIGBUS, similar\nto x86 when MEMORY_FAILURE is not configured. Also print unexpected fault\nflags, for easier debugging.\n\nNote that VM_FAULT_HWPOISON_LARGE is not expected, because s390 cannot\nsupport swap entries on other levels than PTE level."

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.
