CVE-2025-39701

Description

In the Linux kernel, the following vulnerability has been resolved:

ACPI: pfr_update: Fix the driver update version check

The security-version-number check should be used rather than the runtime version check for driver updates.

Otherwise, the firmware update would fail when the update binary had a lower runtime version number than the current one.
