CVE-2025-39701
Full vulnerability record from the local CVENow database.
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. [ rjw: Changelog edits ]
