Azure Linux 3.0 安全更新内核 (CVE-2025-22009)

medium Nessus 插件 ID 295545

语言：

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-2025-22009 公告中提及的一个漏洞影响。

 - 已修复 Linux 内核中的下列漏洞：regulator: dummy: force synchronous probing Sometimes I get a NULL pointer dereference at boot time in kobject_get() with the following call stack: anatop_regulator_probe() devm_regulator_register() regulator_register() regulator_resolve_supply() kobject_get() By placing some extra BUG_ON() statements I could verify that this is raised because probing of the 'dummy' regulator driver is not completed ('dummy_regulator_rdev' is still NULL). In the JTAG debugger I can see that dummy_regulator_probe() and anatop_regulator_probe() can be run by different kernel threads (kworker/u4:*). I haven't further investigated whether this can be changed or if there are other possibilities to force synchronization between these two probe routines. On the other hand I don't expect much boot time penalty by probing the 'dummy' regulator synchronously. (CVE-2025-22009)

请注意，Nessus 尚未测试此问题，而是只依据应用程序自我报告的版本号进行判断。
