Pan, > In function pm8001_pci_probe(), on errors that the control flow jumps to > label err_out_ha_free, function pm8001_free() is called. In pm8001_free(), > scsi_host_put() is called to release shost, which keeps the return value > of scsi_host_alloc(). After pm8001_free() returns, kfree() is called to > free shost again, resulting in a double free bug. This patch removes > scsi_host_put() from pm8001_free() and explicitly calls scsi_host_put() > to release Scsi_Host in need. Applied to 4.14/scsi-queue. -- Martin K. Petersen Oracle Linux Engineering
