Vulnerability Title
scsi: qla2xxx: Don't query firmware state while chip is down
Source: CVE Program / CVE List V5
Vulnerability 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.
