scsi: qla2xxx: Bound image count in qla2x00_update_fru_versions()
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Bound image count in qla2x00_update_fru_versions() qla2x00_update_fru_versions() copies the user-supplied BSG request into a fixed 256-byte stack buffer (bsg[DMA_POOL_SIZE]) and then iterates list->count times over the qla_image_version array embedded in that buffer, advancing the image pointer each iteration. count is taken directly from user input with no upper bound, while only (DMA_POOL_SIZE - sizeof(list->count)) / sizeof(struct qla_image_version) = 6 entries actually fit. A larger count walks the image pointer off the end of the stack buffer, reading adjacent kernel stack memory and sending it to the device via qla2x00_write_sfp(). Reject requests whose declared count does not fit in the buffer.
