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

Description A flaw exists in the Linux kernel related to the rapidio subsystem. Specifically, a reference count leak can occur when kfifo alloc fails during device operations. This happens because the reference count of chdev->dev is not decremented using put device(&chdev->dev), leading to a resource leak.

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