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."}],"source":{"advisory":"GHSA-gwgv-6976-hxrg","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-16T19:22:51.330478Z","id":"CVE-2026-102693","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-16T19:23:03.423Z"}}]}}
