CVE-2025-38296 Details
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-virtio,qemu (DT) epc : internal_create_group+0xa22/0xdd8 ra : internal_create_group+0xa22/0xdd8 Call Trace: internal_create_group+0xa22/0xdd8 sysfs_create_group+0x22/0x2e platform_profile_init+0x74/0xb2 do_one_initcall+0x198/0xa9e kernel_init_freeable+0x6d8/0x780 kernel_init+0x28/0x24c ret_from_fork+0xe/0x18 Fix this by checking if ACPI is enabled before trying to create sysfs entries. [ rjw: Subject and changelog edits ]
A vulnerability exists in the Linux kernel's handling of the platform profile driver on non-ACPI platforms. The driver initializes sysfs entries that require ACPI to be enabled, leading to warnings during operation. This issue arises because the initialization was recently shifted to the module's init call, without proper checks for ACPI availability.
The vulnerability has been addressed by modifying the driver to check for ACPI availability before creating sysfs entries. Users should ensure they are running a version of the Linux kernel that includes this fix.
