medium Nessus 插件 ID 295083

简介

远程 Azure Linux 主机缺少一个或多个安全更新。

描述

远程 Azure Linux 3.0 主机上安装的内核版本低于 测试的版本。因此,该程序受到 CVE-2024-46711 公告中提及的一个漏洞影响。

- 已修复 Linux 内核中的下列漏洞:mptcp: pm: fix ID 0 endp usage after multiple re-creations 'local_addr_used' and 'add_addr_accepted' are decremented for addresses not related to the initial subflow (ID0), because the source and destination addresses of the initial subflows are known from the beginning: they don't count as additional local address being used or ADD_ADDR being accepted. It is then required not to increment them when the entrypoint used by the initial subflow is removed and re-added during a connection. Without this modification, this entrypoint cannot be removed and re-added more than once. (CVE-2024-46711)
