The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: bounds-check link_id     in ieee80211_ml_epcs IEEE80211_MLE_STA_EPCS_CONTROL_LINK_ID is 0x000f, so link_id extracted from a     PRIO_ACCESS ML element PER_STA_PROFILE subelement can be 0..15. sdata->link[] has     IEEE80211_MLD_MAX_NUM_LINKS (15) entries (indices 0..14), making index 15 out-of-bounds. A connected WiFi     7 AP can trigger this by sending an EPCS Enable Response action frame with a PER_STA_PROFILE subelement     where link_id = 15. The unsolicited-notification path (dialog_token = 0) is reachable any time EPCS is     already enabled, without any prior client request. sdata->link[15] reads into the first word of     sdata->activate_links_work (a wiphy_work whose embedded list_head is non-NULL after INIT_LIST_HEAD), so     the NULL check on the result does not catch the invalid access. The garbage pointer is then passed to     ieee80211_sta_wmm_params(), which dereferences link->sdata and crashes the kernel. The same class of bug     was fixed for ieee80211_ml_reconfiguration() by commit 162d331d833d (wifi: mac80211: bounds-check link_id     in ieee80211_ml_reconfiguration). (CVE-2026-64030)

Note that Nessus relies on the presence of the package as reported by the vendor.
