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

Description: The issue is related to the macsec component of the Linux kernel, which causes a resource leak when handling the NETDEV UNREGISTER event due to the underlay driver not being notified to clean its macsec offload resources. This can lead to a denial of service. The fix involves moving offload handling from macsec dellink() to macsec common dellink() when handling the NETDEV UNREGISTER event.

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