Description
In the Linux kernel, the following vulnerability has been resolved: mcb: mcb-parse: fix error handing in chameleon_parse_gdd() If mcb_device_register() returns error in chameleon_parse_gdd(), the refcount of bus and device name are leaked. Fix this by calling put_device() to give up the reference, so they can be released in mcb_release_dev() and kobject_cleanup().

Executive Summary

This vulnerability is in the Linux kernel's mcb component, specifically in the mcb-parse function chameleon_parse_gdd(). When the function mcb_device_register() returns an error, the reference counts for the bus and device name are not properly released, causing a reference count leak. The fix involves calling put_device() to release these references so they can be properly cleaned up later.

Impact Analysis

The vulnerability causes a reference count leak in the Linux kernel, which can lead to resource leaks. Over time, this may result in increased memory usage or resource exhaustion, potentially affecting system stability or performance.
