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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97571","source_modified_at":"2026-10-19T09:09:33.921Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","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"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97571","source_modified_at":"2026-10-19T09:09:33.921Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","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","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97571","source_modified_at":"2026-10-19T09:09:33.921Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"37e08dc821a57fe0592c917486b638caa888b46d","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97571","source_modified_at":"2026-10-19T09:09:33.921Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6.12.112","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.002,"percentile":0.09304,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:21:56.208Z","modified_at":"2026-10-19T09:09:33.921Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97571","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:09:33.921Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97571","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/d7db2e4953e4626339fd0075564a3e447650d37b"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/c8050386a2209b2a474c1eb4bd1574dc19129bfb"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/37e08dc821a57fe0592c917486b638caa888b46d"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/b814dfbfeb0a68c9a52073f2caa05a2d5247a329"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:09:33.921Z","content_hash":"215754396b68abd6cb2c6ef9ab1d6ae3659bda909044f971c353367f00a9b0c5"}}
