They are just zero cleared. The function mpi3mr_complete_evt_ack() refers host_tag field of the elements. Due to the zero value of the host_tag field, the function calls clear_bit() for mrico-&gt;evtack_cmds_bitmap with wrong bit index. This results in memory access to invalid address and &#34;BUG: KASAN: use-after-free&#34;. This BUG was observed at eHBA-9600 firmware update to version 8.3.1.0. To fix it, add the missing initialization of mrioc-&gt;evtack_cmds.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>scsi: mpi3mr: Fix missing mrioc-&gt;evtack_cmds initialization</p> <p>Commit c1af985d27da (&#34;scsi: mpi3mr: Add Event acknowledgment logic&#34;) introduced an array mrioc-&gt;evtack_cmds but initialization of the array elements was missed.
