In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Fix use-after-free in lpfc_unreg_rpi() routine An error is detected with the following report when unloading the driver: "KASAN: use-after-free in lpfc_unreg_rpi+0x1b1b" The NLP_REG_LOGIN_SEND nlp_flag is set in lpfc_reg_fab_ctrl_node(), but the flag is not cleared upon completion of the login. This allows a second call to lpfc_unreg_rpi() to proceed with nlp_rpi set to LPFC_RPI_ALLOW_ERROR. This results in a use after free access when used as an rpi_ids array index. Fix by clearing the NLP_REG_LOGIN_SEND nlp_flag in lpfc_mbx_cmpl_fc_reg_login().
