CVE-2025-40343

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

Description A flaw exists in the Linux kernel’s nvmet-fc subsystem where shutting down a port via the configfs interface can lead to a double scheduling of association deletion. This occurs because both nvmet port del ctrls() and nvmet disable port() schedule remaining associations for deletion. The current implementation checks for scheduled deletions after the work item is already scheduled, potentially resulting in the same work item being scheduled again after resources have been freed. The association list is an RCU list, preventing direct locking and requiring a flag to determine if an association is already being deleted.

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