Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> scsi: qla2xxx: Fix response queue over-consumption in __qla_consume_iocb()<br /> <br /> qla24xx_process_response_queue() advances ring_ptr past the head IOCB<br /> before dispatching, so by the time __qla_consume_iocb() runs, ring_ptr<br /> already points at the first continuation IOCB. The function however<br /> looped purex-&gt;entry_count times starting at ring_ptr. As entry_count<br /> includes the head, this consumed one entry too many: it stamped<br /> RESPONSE_PROCESSED on the next, unrelated IOCB and advanced the ring<br /> past it, silently dropping a legitimate firmware response. The head<br /> IOCB&amp;#39;s signature was also never marked.<br /> <br /> Mark the head processed and account for it, then consume only the<br /> entry_count - 1 continuation IOCBs, matching __qla_copy_purex_to_buffer().
