In the Linux kernel, the following vulnerability has been resolved: nvmet-fc: move lsop put work to nvmetfclsreqop It’s possible for more than one async command to be in flight from _nvmetfcsendlsreq. 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 nvmetfclsreq_op struct, which already tracks all resources related to the command.
