Linux Distros 未修補弱點：CVE-2026-13573
medium Nessus Plugin ID 323920
語言:
概要
Linux/Unix 主機上安裝的一個或多個套件存有弱點，廠商表示將不會修補。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。- 在 llvm llvm-project 中發現弱點，直到 22.1.6。這會影響元件 ValueSymbolTable 模組的程式庫 /lib/IR/ValueSymbolTable.cpp 中的函式 llvm：：StringMap：：insert。操控會導致堆疊型緩衝區溢位。在本機攻擊是必要條件。該漏洞已公開，且可能被利用。目前尚不確定是否存在此弱點。LLVM 專案解釋說，報告的行為超出了其記錄的安全範圍，因此不被視為安全漏洞。（CVE-2026-13573）
請注意，Nessus 的判定取決於廠商所報告的套件是否存在。
