The issue occurs when a\nLAN client initiates a connection to a malicious RTSP server controlled by an\nattacker. A specially crafted RTSP message may trigger improper memory handling\nwithin the kernel module\n\n\n\n\n\n\n\n\n\nSuccessful\nexploitation of this vulnerability may result in a denial-of-service (DoS)\ncondition or allow remote code execution (RCE), potentially leading to full\ncompromise of the device. This vulnerability can be exploited by an\nunauthenticated attacker under the device's default configuration.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":null,"cwes":["CWE-121"],"references":["https://www.tp-link.com/en/support/download/tl-wr940n/v6/#Firmware","https://www.tp-link.com/jp/support/download/tl-wr940n/v6/#Firmware","https://www.tp-link.com/us/support/download/tl-wr940n/v6/#Firmware","https://www.tp-link.com/us/support/faq/5213/"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:27.712498749+00:00"},"epss":{"cve":"CVE-2026-12935","score":0.00986,"percentile":0.62135,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
