Linux Distros 未修補的弱點：CVE-2024-36905
medium Nessus Plugin ID 229095
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，且供應商未提供可用的修補程式。- tcp延遲關機 (SEND_SHUTDOWN) TCP_SYN_RECV 通訊端。TCP_SYN_RECV 狀態很特殊只有 crosssyn 連線使用此連線主要由 fuzzer 使用。在接下來的當機 [1] 中syzbot 設法在 tcp_rcv_space_adjust() 中觸發除以零。通訊端進行下列狀態轉換而從未呼叫 tcp_init_transfer()這表示也不會呼叫 tcp_init_buffer_space()。TCP_CLOSE connect() TCP_SYN_SENT TCP_SYN_RECV shutdown() -> tcp_shutdown(sk, SEND_SHUTDOWN) TCP_FIN_WAIT1 若要修正此問題請將 tcp_shutdown() 變更為不執行 TCP_SYN_RECV -> TCP_FIN_WAIT1 的轉換否則此方法沒有任何意義。當 tcp_rcv_state_process() 稍後將通訊端狀態從 TCP_SYN_RECV 變更為 TCP_ESTABLISH 時然後查看 sk->sk_shutdown 以最終進入 TCP_FIN_WAIT1 狀態並從合理的通訊端狀態傳送 FIN 封包。這表示現在可從 BH 內容呼叫 tcp_send_fin()且必須使用 GFP_ATOMIC 配置。
