  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Zero mailbox struct in qla2x00_get_firmware_state()\n\nThe mbx_cmd_t is allocated on the stack but left uninitialized.\nqla2x00_mailbox_command() has several early-return paths (PCI permanent\nfailure, device failed, EEH busy, ISP abort pending, mailbox access\ntimeout, purge mbox) that return without writing the input mailbox\nregisters back into mcp->mb[]. qla2x00_get_firmware_state() then\nunconditionally copies mcp->mb[1..6] (and mb[12]) into the caller's\nstates[] array regardless of the return value.\n\nOn such a failure the copied values are uninitialized kernel stack\nmemory, which is then exposed to userspace via the fw_state and\nmpi_fw_state sysfs handlers. Zero the mailbox struct so a failed query\nyields deterministic zeroed state instead of leaking stack contents.",
