platform/x86: hp-bioscfg: Fix kobject warnings for empty attribute names

Assigner: Linux
Reserved: 13.01.2026 Published: 14.02.2026 Updated: 14.02.2026

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

platform/x86: hp-bioscfg: Fix kobject warnings for empty attribute names

The hp-bioscfg driver attempts to register kobjects with empty names when the HP BIOS returns attributes with empty name strings. This causes multiple kernel warnings:

kobject: (00000000135fb5e6): attempted to be registered with empty name! WARNING: CPU: 14 PID: 3336 at lib/kobject.c:219 kobject_add_internal+0x2eb/0x310

Add validation in hp_init_bios_buffer_attribute() to check if the attribute name is empty after parsing it from the WMI buffer. If empty, log a debug message and skip registration of that attribute, allowing the module to continue processing other valid attributes.
