That helper\nassumes a BASIC MLE with enough common info and documents that\ncallers must first use ieee80211_mle_type_ok().\n\nAttack chain:\nmalicious AP sends a short EHT MLE in an MBSSID beacon.\ncfg80211_inform_bss_frame_data() stores the copied IE buffer.\ncfg80211_parse_mbssid_data() builds the nontransmitted BSS IE.\ncfg80211_gen_new_ie() sees the EHT MLE in the parent frame.\nieee80211_mle_get_mld_id() then reads past the IE boundary.\n\nValidate the MLE type and size before reading the MLD ID. This\nmatches the contract required by the MLE helper and rejects the\nshort element before any internal MLE fields are accessed.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","score":8.1},"cwes":["CWE-125"],"references":["https://git.kernel.org/stable/c/3b0505e43da8fb5b2a7994c3c3604e5a74692154","https://git.kernel.org/stable/c/584657c5fc58d7a840623a2fa06331c9661dd0f1","https://git.kernel.org/stable/c/74e27cd1d98b546fdb276008a83708d062339661"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-68472","score":0.00342,"percentile":0.27509,"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).
