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.
