This\nallows the operation to proceed for non-TDLS stations, causing\nunintended side effects like modifying channel context and HT\nprotection before failing.\n\nAdd a check for sta->sta.tdls early in the ENABLE_LINK case, before\nany side effects occur, to ensure the operation is only allowed for\nactual TDLS peers.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","score":7.1},"cwes":[],"references":["https://git.kernel.org/stable/c/44839ea7e96b3659a1606f3d5267063135479b7c","https://git.kernel.org/stable/c/6813a8b1b240756dad4375f3e020ce10e4e3871b","https://git.kernel.org/stable/c/7d73872d949c488a1d7c308031d6a9d89b5e0a8b","https://git.kernel.org/stable/c/8148c2fda4ebb17104a573649c9b699208ad10ee","https://git.kernel.org/stable/c/ba5b43db126a5e7378553869e3f7954d9187349f"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-43052","score":0.00123,"percentile":0.02061,"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).
