Linux Kernel Memory Leak Vulnerability in DMI Sysfs Handling

A memory leak vulnerability has been identified in the Linux kernel's DMI sysfs management. The issue arises because the function kobject_init_and_add() retains a reference to a kobject even when it fails, leading to improper memory cleanup. The vulnerability has been addressed by ensuring that kobject_put() is called to release the memory associated with the object in case of an error.

Impact

Exploitation of this vulnerability could lead to a memory leak, causing increased memory usage and potentially degrading system performance over time.
