概要
遠端 Azure Linux 主機缺少一個或多個安全性更新。說明
遠端 Azure Linux 3.0 主機上安裝的 hyperv-daemons 版本比測試版舊。因此，此版本會受到 CVE-2024-27009 公告中提及的一個弱點影響。- 已解決 Linux 核心中的下列弱點：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)
