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

Description A memory leak issue has been identified in the Linux kernel, specifically in the coresight subsystem. The problem occurs when device registration fails in the cscfg create device function. According to the documentation for device initialize, using put device() is recommended to release the reference instead of directly freeing the device. This is to prevent potential memory leaks during error handling.

Recommendations To resolve this issue, ensure proper error handling by using put device() instead of directly freeing the device when device register() fails. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
