Linux Distros 未修補的弱點：CVE-2025-38632
medium Nessus Plugin ID 260257
語言:
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，且廠商未提供可用的修補程式。- pinmux修正使用中 mux_usecount 提交 5a3e85c3c397 造成 mux_owner NULL 的爭用 (pinmux使用順序存取來存取 desc->pinmux 資料) 嘗試解決相同 gpio 的兩個用戶端針對相同功能呼叫 pinctrl_select_state() 時所產生的問題在存取 desc->mux_owner 時發生 NULL 指標問題。不過由於處理問題的方式問題並未完全修正而且仍會產生相同的 NULL 指標。此問題是因下列交錯所導致cpu0 (處理程序 A) cpu1 (處理程序 B) pin_request() { pin_free() { mutex_lock() desc->mux_usecount--; //變成 0 .. mutex_unlock() mutex_lock(desc->mux) desc->mux_usecount++; // 變成 1 desc->mux_owner = owner;
mutex_unlock(desc->mux) mutex_lock(desc->mux) desc->mux_owner = NULL mutex_unlock(desc->mux) 此序列導致針腳似乎正在使用中 (`mux_usecount == 1`) 但沒有擁有者 (`mux_owner == NULL`)這可能會在下一個 pin_request 上造成 NULL 指標在相同的針腳上。確保 mux_usecount 和 mux_owner 的更新在相同鎖定下自動執行。只在 mux_usecount 達到零且未指派任何新擁有者時清除 mux_owner。 (CVE-2025-38632)
請注意，Nessus 的判定取決於廠商所報告的套件是否存在。
