CVE-2025-38296

Estado: AnalizadaMedia (5.5)—

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

ACPI: platform_profile: Avoid initializing on non-ACPI platforms

The platform profile driver is loaded even on platforms that do not have ACPI enabled. The initialization of the sysfs entries was recently moved from platform_profile_register() to the module init call, and those entries need acpi_kobj to be initialized which is not the case when ACPI is disabled.

This results in the following warning:

Fix this by checking if ACPI is enabled before trying to create sysfs entries.
