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

Description A refcount leak issue has been identified in the Linux kernel, specifically in the sdhci-of-esdhc component. The of find matching node() function returns a node pointer with an incremented refcount, which should be decremented using of node put() when no longer needed to prevent a refcount leak. The issue arises from a missing of node put() call. The of node put() function also checks for null pointers.

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