What it is

In the Linux kernel, the following vulnerability has been resolved:

scsi: qla2xxx: Fix response queue over-consumption in __qla_consume_iocb()

qla24xx_process_response_queue() advances ring_ptr past the head IOCB

before dispatching, so by the time __qla_consume_iocb() runs, ring_ptr

already points at the first continuation IOCB. The function however

looped purex->entry_count times starting at ring_ptr. As entry_count

includes the head, this consumed one entry too many: it stamped

RESPONSE_PROCESSED on the next, unrelated IOCB and advanced the ring

past it, silently dropping a legitimate firmware response. The head

IOCB's signature was also never marked.

Mark the head processed and account for it, then consume only the

entry_count - 1 continuation IOCBs, matching __qla_copy_purex_to_buffer().
