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 hyperv-daemons 版本低于 测试的 版本。因此，该程序受到 CVE-2024-27009 公告中提及的一个漏洞影响。- 已修复 Linux 内核中的下列漏洞：s390/cio: fix race condition during online processing A race condition exists in ccw_device_set_online() that can cause the online process to fail, leaving the affected device in an inconsistent state. As a result, subsequent attempts to set that device online fail with return code ENODEV. The problem occurs when a path verification request arrives after a wait for final device state completed, but before the result state is evaluated. Fix this by ensuring that the CCW-device lock is held between determining final state and checking result state. Note that since: commit 2297791c92d0 (s390/cio: dont unregister subchannel from child-drivers) path verification requests are much more likely to occur during boot, resulting in an increased chance of this race condition occurring. (CVE-2024-27009)
