Linux Distros 未修补的漏洞：CVE-2026-13573
medium Nessus 插件 ID 323920
语言：
简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- 在 llvm llvm-project 及之前 22.1.6版本中发现一个漏洞。这会影响组件 ValueSymbolTable 模块的库 /lib/IR/ValueSymbolTable.cpp 中的函数 llvm：：StringMap：：insert。这种操纵会导致基于堆栈的缓冲区溢出。本地攻击是一项要求。该漏洞已被公开并可被使用。目前尚不确定是否存在该漏洞。LLVM 项目解释，报告的行为超出了其记录的安全范围，因此不被视为安全漏洞。（CVE-2026-13573）
请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
