Make the minimum-length check follow\nthat exact runtime layout calculation before parsing the payload.\n\nFor new TX API, reject TX_CMD responses with frame_count != 1 and\nwarn/return in the aggregation handler to document that aggregated\naccounting is expected via BA notifications.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93793","source_modified_at":"2026-10-21T12:52:36.442Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"8ca151b568b67a7b72dcfc6ee6ea7c107ddd795c","lessThan":"5e871c03506c529d5fe372d099c1ad1465c7bc38","status":"affected","versionType":"git"},{"version":"8ca151b568b67a7b72dcfc6ee6ea7c107ddd795c","lessThan":"fc14f5fe8a4374ed1088cfbddc1dae4d16c9935b","status":"affected","versionType":"git"},{"version":"8ca151b568b67a7b72dcfc6ee6ea7c107ddd795c","lessThan":"4d942dfc13aec393e003ab28ff58db744c26e6eb","status":"affected","versionType":"git"},{"version":"8ca151b568b67a7b72dcfc6ee6ea7c107ddd795c","lessThan":"8d70881707b47353359df57df12f6de67fdacdd2","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93793","source_modified_at":"2026-10-21T12:52:36.442Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"3.9","status":"affected"},{"version":"0","lessThan":"3.9","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93793","source_modified_at":"2026-10-21T12:52:36.442Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"5e871c03506c529d5fe372d099c1ad1465c7bc38","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93793","source_modified_at":"2026-10-21T12:52:36.442Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"4d942dfc13aec393e003ab28ff58db744c26e6eb","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93793","source_modified_at":"2026-10-21T12:52:36.442Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"8d70881707b47353359df57df12f6de67fdacdd2","basis":"first unaffected version stated in the CVE record"}],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00241,"percentile":0.14463,"score_date":"2026-10-23"},"published_at":"2026-09-24T16:02:26.708Z","modified_at":"2026-10-21T12:52:36.442Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-93793","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:52:36.442Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-93793","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/5e871c03506c529d5fe372d099c1ad1465c7bc38"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/fc14f5fe8a4374ed1088cfbddc1dae4d16c9935b"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/4d942dfc13aec393e003ab28ff58db744c26e6eb"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/8d70881707b47353359df57df12f6de67fdacdd2"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-21T12:52:36.442Z","content_hash":"70fe97cc94d312e202069cc967cbf83b32f113985d6a440c69619571b103c9d4"}}
