概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，供應商表示將不會修補。說明
Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。- 藍牙MGMT修正可能的 UAF此項目嘗試修正可能的 UAF這是因為 mgmt_pending 結構遭到釋放同時仍像在後續追踪中一樣仍在處理程序中所造成的問題以便修正引入並使用 mgmt_pending_valid 檢查是否尚未移除 mgmt_pending 的問題待處理清單上的完整回呼上會使用該清單進行檢查此外在按住 mgmt_pending_lock 的同時從清單中移除 cmd 以避免 TOCTOU 問題因為如果 cmd 留在清單上仍可存取和釋放該 cmd。錯誤：
