{"schema":"threatline.record/2","record":{"id":"CVE-2026-98806","aliases":[],"summary":"octeontx2-pf: Fix aura BPID assignment when CONFIG_DCB is enabled","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nocteontx2-pf: Fix aura BPID assignment when CONFIG_DCB is enabled\n\nPreviously, BPID assignment under CONFIG_DCB assumed\n`queue_to_pfc_map` was always initialized. For SDP VFs this leads to\ninvalid memory access as it was not initialized.\n\nThis patch adds a NULL check for `queue_to_pfc_map` before\ndereferencing it. Also, simplifies the logic by always assigning a\ndefault BPID first, then conditionally overriding it if CONFIG_DCB is\nenabled and the map exists.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98806","source_modified_at":"2026-10-19T09:25:59.674Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"184fb40f731bd3353b0887731f7caba66609e9cd","lessThan":"59fbbded05e559675930fd521b8d62b72828b52d","status":"affected","versionType":"git"},{"version":"184fb40f731bd3353b0887731f7caba66609e9cd","lessThan":"056994563935e049093f100efaad7e63ad113814","status":"affected","versionType":"git"},{"version":"22079d5ae4a33679150f7de89f4107f4e0446886","status":"affected","versionType":"git"},{"version":"6.14.9","lessThan":"6.15","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98806","source_modified_at":"2026-10-19T09:25:59.674Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.15","status":"affected"},{"version":"0","lessThan":"6.15","status":"unaffected","versionType":"semver"},{"version":"7.2.10","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-2026-98806","source_modified_at":"2026-10-19T09:25:59.674Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"59fbbded05e559675930fd521b8d62b72828b52d","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98806","source_modified_at":"2026-10-19T09:25:59.674Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"056994563935e049093f100efaad7e63ad113814","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98806","source_modified_at":"2026-10-19T09:25:59.674Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6.15","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.0018,"percentile":0.0721,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:48:52.707Z","modified_at":"2026-10-19T09:25:59.674Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98806","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:25:59.674Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98806","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/59fbbded05e559675930fd521b8d62b72828b52d"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/056994563935e049093f100efaad7e63ad113814"}],"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":"2026-10-19T09:25:59.674Z","content_hash":"fb46c0f3f51b091a1e07498fa5c5f34ad5d7ae14fec2fe6cdecdbf7bd6c6a654"}}
