CVE-2025-38296 Information

Jul 12, 2025 cve

Description

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:

WARNING: CPU: 5 PID: 1 at fs/sysfs/group.c:131 internal_create_group+0xa22/0xdd8 Modules linked in: CPU: 5 UID: 0 PID: 1 Comm: swapper/0 Tainted: G W 6.15.0-rc7-dirty 6 PREEMPT Tainted: [W]=WARN Hardware name: riscv-virtioqemu (DT) epc : internal_create_group+0xa22/0xdd8 ra : internal_create_group+0xa22/0xdd8

Call Trace:

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