CVE-2025-38296

Boot-time kernel warning via non-ACPI sysfs initialization

Published Jul 10, 2025 · Updated May 11, 2026

Improper initialization in the platform profile driver in Linux 6.14 through 6.15.2 causes a kernel warning during non-ACPI boot. platform_profile_init calls sysfs_create_group for entries that require acpi_kobj even when ACPI is disabled and acpi_kobj is uninitialized. The condition requires a non-ACPI platform; published evidence reports a warning and kernel taint but no attacker-controlled trigger or broader consequence.
