CVE-2022-49224 Details
Description
In the Linux kernel, the following vulnerability has been resolved: power: supply: ab8500: Fix memory leak in ab8500_fg_sysfs_init kobject_init_and_add() takes reference even when it fails. According to the doc of kobject_init_and_add()： If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object. Fix memory leak by calling kobject_put().
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.
