This value is stored directly in vhost-&gt;num_targets without validation, and is then used as the loop bound in ibmvfc_alloc_targets() to index into disc_buf[], which is only allocated for max_targets entries. Indices at or beyond max_targets access kernel memory outside the DMA-coherent allocation. The out-of-bounds data is subsequently embedded in Implicit Logout and PLOGI MADs that are sent back to the VIO server, leaking kernel memory.</p> <p>Fix by clamping num_written to max_targets before storing it.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>scsi: ibmvfc: Fix OOB access in ibmvfc_discover_targets_done()</p> <p>A malicious or compromised VIO server can return a num_written value in the discover targets MAD response that exceeds max_targets.
