Official description

In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Don't query firmware state while chip is down qla2x00_fw_state_show() initializes rval to QLA_FUNCTION_FAILED and jumps to the out: label when the chip is down or EEH is busy. The out: block then re-issued qla2x00_get_firmware_state() because rval != QLA_SUCCESS, defeating the chip-down/EEH-busy guards and issuing a mailbox command (outside optrom_mutex) during ISP reset or PCI error recovery, which can hang the adapter. It also turned a normal in-lock mailbox failure into a second unsynchronized mailbox attempt. Make the out: fallback only mark the firmware state as unknown. The mailbox is now issued at most once, inside optrom_mutex, and only when the chip is up and not EEH-busy.
