S1G and\nregular association responses also have different IE offsets, but the\nS1G path only patched resp_ie after the unsafe initialiser had already\nrun.\n\nDefer resp_ie, resp_ie_len, and status to after the link-iteration\nloop. Use a bool to remember whether the frame is S1G, then validate\nthe appropriate minimum length and set all three fields in a single\nif/else block. Funnel short-frame and SME-reject cleanup through a\nshared free_bss label for the abandon paths.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93806","source_modified_at":"2026-10-03T10:57:39.214Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Linux","vendor":"Linux","versions":[{"version":"6829c878ecd24ff0ae41b4668c7e9d0f11b66942","lessThan":"3bcaaaa4ad334053ceea2ea2f0623f22afe2e1ac","status":"affected","versionType":"git"},{"version":"6829c878ecd24ff0ae41b4668c7e9d0f11b66942","lessThan":"71be658246c903b9e96976a23c23800675896a1b","status":"affected","versionType":"git"},{"version":"6829c878ecd24ff0ae41b4668c7e9d0f11b66942","lessThan":"a57310600c1e2b9ada0f37c96e8f48aef47d3093","status":"affected","versionType":"git"},{"version":"6829c878ecd24ff0ae41b4668c7e9d0f11b66942","lessThan":"78ac450ad4624d6b2999cb4eeb28916767f81247","status":"affected","versionType":"git"},{"version":"6829c878ecd24ff0ae41b4668c7e9d0f11b66942","lessThan":"b760113aeca2e9362d56bf9e9263373ffe6c8eb3","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93806","source_modified_at":"2026-10-03T10:57:39.214Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Linux","vendor":"Linux","versions":[{"version":"2.6.32","status":"affected"},{"version":"0","lessThan":"2.6.32","status":"unaffected","versionType":"semver"},{"version":"6.1.189","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.158","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-2026-93806","source_modified_at":"2026-10-03T10:57:39.214Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Linux","ecosystem":null},"version":"3bcaaaa4ad334053ceea2ea2f0623f22afe2e1ac","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93806","source_modified_at":"2026-10-03T10:57:39.214Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Linux","ecosystem":null},"version":"71be658246c903b9e96976a23c23800675896a1b","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93806","source_modified_at":"2026-10-03T10:57:39.214Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Linux","ecosystem":null},"version":"78ac450ad4624d6b2999cb4eeb28916767f81247","basis":"first unaffected version stated in the CVE record"}],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00254,"percentile":0.15982,"score_date":"2026-10-23"},"published_at":"2026-09-24T16:02:40.159Z","modified_at":"2026-10-03T10:57:39.214Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-93806","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-03T10:57:39.214Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-93806","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/3bcaaaa4ad334053ceea2ea2f0623f22afe2e1ac"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/71be658246c903b9e96976a23c23800675896a1b"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/a57310600c1e2b9ada0f37c96e8f48aef47d3093"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/78ac450ad4624d6b2999cb4eeb28916767f81247"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/b760113aeca2e9362d56bf9e9263373ffe6c8eb3"}],"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":"2026-10-03T10:57:39.214Z","content_hash":"d93c406136eb2f3ad62b42c32ce75d73f11a605a24b86471c7a107828e20e885"}}
