{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/83478?format=json","vulnerability_id":"VCID-myk9-yd8r-8bcv","summary":"TinyOS versions up to and including 2.1.2 contain a stack-based buffer overflow vulnerability in the mcp2200gpio utility. The vulnerability is caused by unsafe use of strcpy() and strcat() functions when constructing device paths during automatic device discovery. A local attacker can exploit this by creating specially crafted filenames under /dev/usb/, leading to stack memory corruption and application crashes.","aliases":[{"alias":"CVE-2026-22212"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-22212","reference_id":"","reference_type":"","scores":[{"value":"0.00018","scoring_system":"epss","scoring_elements":"0.05042","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-22212"},{"reference_url":"https://seclists.org/fulldisclosure/2026/Jan/14","reference_id":"14","reference_type":"","scores":[{"value":"4.8","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2026-01-13T19:06:12Z/"}],"url":"https://seclists.org/fulldisclosure/2026/Jan/14"},{"reference_url":"https://github.com/tinyos/tinyos-main","reference_id":"tinyos-main","reference_type":"","scores":[{"value":"4.8","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2026-01-13T19:06:12Z/"}],"url":"https://github.com/tinyos/tinyos-main"},{"reference_url":"https://www.vulncheck.com/advisories/tinyos-stack-based-buffer-overflow-in-mcp2200gpio","reference_id":"tinyos-stack-based-buffer-overflow-in-mcp2200gpio","reference_type":"","scores":[{"value":"4.8","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2026-01-13T19:06:12Z/"}],"url":"https://www.vulncheck.com/advisories/tinyos-stack-based-buffer-overflow-in-mcp2200gpio"}],"weaknesses":[{"cwe_id":121,"name":"Stack-based Buffer Overflow","description":"A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function)."}],"exploits":[],"severity_range_score":"4.8 - 4.8","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-myk9-yd8r-8bcv"}
