Last updated on: 2026-08-17

Assigner: kernel.org

Description

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: vsie: Add missing radix_tree_preload() in _gaccess_shadow_fault() Add missing radix_tree_preload() in _gaccess_shadow_fault() to guarantee forward progress. The core of _gaccess_shadow_fault() has been split into ___gaccess_shadow_fault() in order to simplify locking.

Executive Summary

This is a Linux kernel vulnerability in the KVM (Kernel-based Virtual Machine) subsystem for s390 architecture. It involves a missing radix_tree_preload() call in the _gaccess_shadow_fault() function, which could affect memory access operations in virtual machines.

Detection Guidance

This vulnerability is specific to the Linux kernel's KVM s390 implementation and involves a missing radix_tree_preload() call in the _gaccess_shadow_fault() function. Detection requires checking kernel versions and applying patches rather than running specific commands.

Impact Analysis

The vulnerability may cause forward progress issues in virtual machine memory access operations, potentially leading to crashes or performance degradation in KVM-based virtualization on s390 systems.

Compliance Impact

This vulnerability does not provide sufficient information to determine its impact on compliance with standards like GDPR or HIPAA. The CVE describes a Linux kernel issue in KVM for s390 architecture but lacks details on data exposure, access control, or confidentiality implications required for such assessments.

Mitigation Strategies

Update the Linux kernel to the latest patched version to resolve this vulnerability. Monitor vendor advisories for kernel updates specific to your distribution.
