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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/broadcom/bnxt/bnxt.c"],"versions":[{"version":"0997443906b96a051011f220a61e6dce4602ec54","lessThan":"d7db2e4953e4626339fd0075564a3e447650d37b","status":"affected","versionType":"git"},{"version":"bd649c5cc958169b8a8a3e77ea926d92d472b02a","lessThan":"c8050386a2209b2a474c1eb4bd1574dc19129bfb","status":"affected","versionType":"git"},{"version":"bd649c5cc958169b8a8a3e77ea926d92d472b02a","lessThan":"37e08dc821a57fe0592c917486b638caa888b46d","status":"affected","versionType":"git"},{"version":"bd649c5cc958169b8a8a3e77ea926d92d472b02a","lessThan":"b814dfbfeb0a68c9a52073f2caa05a2d5247a329","status":"affected","versionType":"git"},{"version":"6.12.20","lessThan":"6.12.112","status":"affected","versionType":"semver"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/net/ethernet/broadcom/bnxt/bnxt.c"],"versions":[{"version":"6.13","status":"affected"},{"version":"0","lessThan":"6.13","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.12.20","versionEndExcluding":"6.12.112"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.13","versionEndExcluding":"6.18.53"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.13","versionEndExcluding":"7.2.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.13","versionEndExcluding":"7.3-rc3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/d7db2e4953e4626339fd0075564a3e447650d37b"},{"url":"https://git.kernel.org/stable/c/c8050386a2209b2a474c1eb4bd1574dc19129bfb"},{"url":"https://git.kernel.org/stable/c/37e08dc821a57fe0592c917486b638caa888b46d"},{"url":"https://git.kernel.org/stable/c/b814dfbfeb0a68c9a52073f2caa05a2d5247a329"}],"title":"bnxt_en: Propagate TPA buffer allocation failures in bnxt_queue_mem_alloc()","x_generator":{"engine":"bippy-1.2.0"}}}}
