In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
bnxt_en: Propagate TPA buffer allocation failures in bnxt_queue_mem_alloc()<\/p>\n
bnxt_alloc_one_tpa_info_data() returns -ENOMEM as soon as one allocation
\nfails. This leaves the remaining rxr->rx_tpa[] entries zeroed.<\/p>\n
bnxt_queue_mem_alloc() discards that return value, so the partially
\ninitialized ring is installed by bnxt_queue_start().<\/p>\n
Since the agg_id is picked by the hardware and bnxt_alloc_agg_idx maps
\nit to a SW index in rxr->rx_tpa[], it is possible that an uninitialized
\nslot can be chosen which would hand a zero DMA address to the device.<\/p>\n
Fix this by checking the return value of bnxt_alloc_one_tpa_info_data
\nand unwinding, freeing the ring buffers.<\/p>\n","protected":false},"excerpt":{"rendered":"
