The binary reads the /proc/stat file using fgets() into a local buffer and subsequently parses the line using sscanf() into a single-byte variable with the %s format specifier. Maliciously crafted /proc/stat content can overwrite adjacent stack memory, potentially allowing an attacker with filesystem write privileges to execute arbitrary code on the device."}], "lastModified": "2025-11-17T21:50:14.877", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:totolink:a720r_firmware:4.1.5cu.614_b20230630:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "BCA249C9-68D4-48FE-B0CA-77ECF53DDE3B"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:totolink:a720r:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "A1DE5168-B787-462C-B024-2B8F73759034"}], "operator": "OR"}], "operator": "AND"}], "sourceIdentifier": "cve@mitre.org"}
