CVE-2026-89850

CVE-2026-89850 affects the Linux kernel qla2xxx SCSI driver . In qla2x00_fw_state_show(), when the chip is down or EEH is busy, rval is set to QLA_FUNCTION_FAILED and execution jumps to the out: label, which then re-issues qla2x00_get_firmware_state() because rval != QLA_SUCCESS. This defeats the...
