This value is\nstored directly in vhost->num_targets without validation, and is then used\nas the loop bound in ibmvfc_alloc_targets() to index into disc_buf[], which\nis only allocated for max_targets entries. Indices at or beyond max_targets\naccess kernel memory outside the DMA-coherent allocation.  The\nout-of-bounds data is subsequently embedded in Implicit Logout and PLOGI\nMADs that are sent back to the VIO server, leaking kernel memory.\n\nFix by clamping num_written to max_targets before storing it.",
