Ben Widawsky 88ff5d466c cxl/mem: Fix potential memory leak ... When submitting a command for userspace, input and output payload bounce buffers are allocated. For a given command, both input and output buffers may exist and so when allocation of the input buffer fails, the output buffer must be freed too. As far as I can tell, userspace can't easily exploit the leak to OOM a machine unless the machine was already near OOM state.
