The\nFUNC_CTRL case then further casts to struct btmtk_hci_wmt_evt_funcc\nand reads its 2-byte status field, again without a length check.\nFirmware that sends a short or malformed WMT event makes both drivers\nread past the end of the received SKB.\n\nMirror btmtk.c: validate the base WMT header with skb_pull_data()\nbefore touching any of its fields, and when a FUNC_CTRL event turns\nout to be the short, header-only form (a plain enable/disable ack\nwith no status word), decode the result from the header's own flag\nbyte instead (0 = success, otherwise failure).\n\nVerified setup on MT7920, MT7921, MT7922 and MT7925: no regression.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98292","source_modified_at":"2026-10-19T09:17:03.377Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"e0b67035a90b58d01f911fed77b6e3da153da66e","lessThan":"5a5cfd8488c97e1b8939515429fe4c81e9f2df4f","status":"affected","versionType":"git"},{"version":"e0b67035a90b58d01f911fed77b6e3da153da66e","lessThan":"8879e3e0a84a86954c855caceead4867e74a9a27","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98292","source_modified_at":"2026-10-19T09:17:03.377Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"5.1","status":"affected"},{"version":"0","lessThan":"5.1","status":"unaffected","versionType":"semver"},{"version":"7.2.8","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-2026-98292","source_modified_at":"2026-10-19T09:17:03.377Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"5a5cfd8488c97e1b8939515429fe4c81e9f2df4f","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98292","source_modified_at":"2026-10-19T09:17:03.377Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"8879e3e0a84a86954c855caceead4867e74a9a27","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00162,"percentile":0.05097,"score_date":"2026-10-23"},"published_at":"2026-10-06T08:45:51.807Z","modified_at":"2026-10-19T09:17:03.377Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98292","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:17:03.377Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98292","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/5a5cfd8488c97e1b8939515429fe4c81e9f2df4f"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/8879e3e0a84a86954c855caceead4867e74a9a27"}],"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":"2026-10-19T09:17:03.377Z","content_hash":"db014766811ab0d02a4e4a0effa63d4e7ee260584c32163590078f80a374d079"}}
