{"schema":"threatline.record/2","record":{"id":"CVE-2026-102693","aliases":["GHSA-gwgv-6976-hxrg"],"summary":"RIOT: Remote Stack Buffer Overflow in ATWINC15x0 driver via unsanitized SSID","details":"RIOT is an open-source microcontroller operating system designed for Internet of Things devices and other embedded systems. Prior to 2026.04, the ATWINC15x0 driver's _atwinc15x0_sta_set_current_ssid function uses strcpy to copy an SSID without checking the destination size. When MODULE_ATWINC15X0_DYNAMIC_CONNECT is enabled, a nearby attacker can advertise a malformed or oversized SSID that is processed during Wi-Fi scanning, causing memory corruption and potentially a hard fault, denial of service, or code execution. This issue is fixed in version 2026.04.","categories":["Unclassified"],"product":"RIOT","vendor":"RIOT-OS","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102693","source_modified_at":"2026-10-16T19:23:03.423Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"RIOT","vendor":"RIOT-OS","versions":[{"version":"< 2026.04","status":"affected"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/RIOT-OS/RIOT/security/advisories/GHSA-gwgv-6976-hxrg","source_modified_at":"2026-09-29T17:22:39Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"ecosystem":"","name":"RIOT-OS/RIOT"},"range":"<= master"}],"fixed_versions":[],"cvss":9.6,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00226,"percentile":0.12558,"score_date":"2026-10-23"},"published_at":"2026-10-16T16:49:45.584Z","modified_at":"2026-10-16T19:23:03.423Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102693","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-16T19:23:03.423Z"},{"source":"GitHub Advisory Database","url":"https://github.com/RIOT-OS/RIOT/security/advisories/GHSA-gwgv-6976-hxrg","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-09-29T17:22:39Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102693","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/RIOT-OS/RIOT/security/advisories/GHSA-gwgv-6976-hxrg","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/RIOT-OS/RIOT/commit/5209c1b84f9771342f079b7d5d94d8207fdd5f0a","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/RIOT-OS/RIOT/releases/tag/2026.04","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-16T19:22:51.330478Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-16T19:23:03.423Z","content_hash":"ed868853fed278fbb20e73eac5b5d6ac31e814ae86f3e0dc14e34be46689749f"}}
