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。

  - PM: hibernate避免 hibernate_compressor_param_set() 中的鎖死 syzbot 報告 lock_system_sleep() 中的鎖死 (請參閱下文)。/sys/module/hibernate/parameters/compressor 的寫入作業與 ieee80211 裝置的註冊相衝突進而在嘗試取得 param_lock 下的 system_transition_mutex 時導致鎖死。為避免此鎖死狀況請將 hibernate_compressor_param_set() 變更為使用 mutex_trylock() 嘗試取得 system_transition_mutex並在失敗時傳回 -EBUSY。
    呼叫 mutex_trylock(&system_transition_mutex) 之前不需要儲存或調整工作旗標因為呼叫者最終不會等待此 mutex而且如果它在進行中的系統暫停同時執行則其返回使用者空間時將正確凍結。 syzbot 報告 syz-executor895/5833 嘗試取得鎖定 ffffffff8e0828c8 (system_transition_mutex){+.+.}-{4:4}位於
