CVE intelligence and bounded remediation

CVE-2025-37877 — Linux Linux Kernel security vulnerability

Medium CVSS 5.5

In the Linux kernel, the following vulnerability has been resolved: iommu: Clear iommu-dma ops on cleanup If iommu_device_register() encounters an error, it can end up tearing down already-configured groups and default domains, however this currently still leaves devices hooked up to iommu-dma (and even historically the behaviour in this area was at best inconsistent across architectures/drivers...) Although in the case that an IOMMU is present whose driver has failed to probe, users cannot necessarily expect DMA to work anyway, it's still arguable that we should do our best to put things back as if the IOMMU driver was never there at all, and certainly the potential for crashing in iommu-dma itself is undesirable. Make sure we clean up the dev->dma_iommu flag along with everything else.

Matched remediation archetype

General vulnerability remediation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
