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 bcma mdio mii register function related to the bgmac Ethernet driver. The of get child by name() 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.
Recommendations To resolve this issue, apply the fix that adds the missing of node put() call to avoid the refcount leak. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
