This leaves the remaining rxr->rx_tpa[] entries zeroed.\n\nbnxt_queue_mem_alloc() discards that return value, so the partially\ninitialized ring is installed by bnxt_queue_start().\n\nSince 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.\n\nFix this by checking the return value of bnxt_alloc_one_tpa_info_data\nand unwinding, freeing the ring buffers.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/37e08dc821a57fe0592c917486b638caa888b46d","tags":[]},{"url":"https://git.kernel.org/stable/c/b814dfbfeb0a68c9a52073f2caa05a2d5247a329","tags":[]},{"url":"https://git.kernel.org/stable/c/c8050386a2209b2a474c1eb4bd1574dc19129bfb","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
