Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the Linux kernel where a reference count leak can occur within the chameleon parse gdd() function if mcb device register() returns an error. Specifically, if an error occurs during device registration, the reference counts for the bus and device name are not properly released, leading to a memory leak. The issue is addressed by calling put device() to relinquish the reference, allowing for proper release in mcb release dev() and kobject cleanup().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
