3Description
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.
Analysis
The HP BIOS configuration driver in the Linux kernel fails to validate attribute names before kobject registration, causing kernel warnings and potential denial of service when HP BIOS returns empty name strings. A local user with standard privileges can trigger this vulnerability to crash or destabilize the system by supplying malformed BIOS attribute data. …
