Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A flaw exists in the Linux kernel where multiple asynchronous commands can be in flight from the nvmet fc send ls req function, potentially leading to a leaked tgtport reference. The issue arises because only one put work item is queued at a time, and the current code does not properly manage resource cleanup when multiple commands are active. Moving the work item to the nvmet fc ls req op struct, which already tracks related resources, resolves this.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
