Linux Kernel Memory Leak Vulnerability in Power Supply AB8500

Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's power supply management for the AB8500 component. The issue arises in the 'ab8500_fg_sysfs_initkobject_init_and_add()' function, which improperly retains a reference to a kobject even when an initialization error occurs. This oversight can lead to a memory leak, as the allocated memory for the kobject is not released. The vulnerability has been addressed by modifying the function to call 'kobject_put()' for proper memory management.

Impact

Exploitation of this vulnerability could lead to a memory leak, causing increased memory usage and potentially leading to memory exhaustion over time.
