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.","state":0,"publishedAt":"2026-10-16T16:49:45.584+00:00","modifiedAt":"2026-10-16T19:23:03.423+00:00","affected":[{"ecosystem":"Vendor product","name":"RIOT","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"RIOT-OS\",\n                    \"product\": \"RIOT\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2026.04\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":9.6,"severity":"CRITICAL"}],"references":["https://github.com/RIOT-OS/RIOT/security/advisories/GHSA-gwgv-6976-hxrg","https://github.com/RIOT-OS/RIOT/commit/5209c1b84f9771342f079b7d5d94d8207fdd5f0a","https://github.com/RIOT-OS/RIOT/releases/tag/2026.04"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102693","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102693","identifiers":["CVE-2026-102693"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
