CVE-2026-31601
MediumSummary
In the Linux kernel, a page fault occurs in the vfio/xe driver when resetting VF devices that do not support migration. The fix reorganizes initialization to decouple migration from reset.
Risk Assessment
The risk involves potential system hangs or crashes in virtualization services when resetting non-migration-capable VF devices, leading to downtime in virtual environments.
Recommendation
Immediately update the Linux kernel to a version containing the fix (commit reorganizing vfio/xe initialization). Avoid resetting VF devices without migration support until the patch is applied.
