This issue affects the function setVlan of the file /goform/setVlan. Such manipulation of the argument vlan_set leads to stack-based buffer overflow. The attack may be launched remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.","cvssScore":9.9,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","cwes":["CWE-119","CWE-121"],"vendors":[],"products":[],"references":[{"url":"https://github.com/wudipjq/my_vuln/blob/main/Linksys3/vuln_67/67.md","tags":[]},{"url":"https://vuldb.com/cve/CVE-2026-108893","tags":[]},{"url":"https://vuldb.com/submit/973112","tags":[]},{"url":"https://vuldb.com/vuln/416685","tags":[]},{"url":"https://vuldb.com/vuln/416685/cti","tags":[]},{"url":"https://www.linksys.com/","tags":[]}],"exploitRefs":[{"url":"https://github.com/wudipjq/my_vuln/blob/main/Linksys3/vuln_67/67.md","tags":[]}],"hasPoc":true,"ai":{"summary":"A stack-based buffer overflow vulnerability exists in Linksys E1700 routers in the setVlan function, allowing remote attackers to execute arbitrary code with high impact.
