Description
In the Linux kernel, the following vulnerability has been resolved: nvmet-fc: move lsop put work to nvmet_fc_ls_req_op It’s possible for more than one async command to be in flight from __nvmet_fc_send_ls_req. For each command, a tgtport reference is taken. In the current code, only one put work item is queued at a time, which results in a leaked reference. To fix this, move the work item to the nvmet_fc_ls_req_op struct, which already tracks all resources related to the command.

Executive Summary

This vulnerability in the Linux kernel's nvmet-fc component involves improper handling of asynchronous commands. Specifically, multiple async commands can be in flight from __nvmet_fc_send_ls_req, each taking a tgtport reference. However, the code only queues one put work item at a time, causing a leaked reference. The fix involves moving the work item to the nvmet_fc_ls_req_op struct, which properly tracks all resources related to each command.

Impact Analysis

The vulnerability can lead to resource leaks in the Linux kernel's nvmet-fc subsystem due to leaked tgtport references. This could potentially degrade system stability or performance over time as resources are not properly released.
