Azure Linux 3.0 安全性更新核心 (CVE-2025-37987)

medium Nessus Plugin ID 295524

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 主機上安裝的核心版本比測試版舊。因此,此版本會受到 CVE-2025-37987 公告中提及的一個弱點影響。

- 已解決 Linux 核心中的下列弱點:pds_core: Prevent possible adminq overflow/stuck condition The pds_core's adminq is protected by the adminq_lock, which prevents more than 1 command to be posted onto it at any one time. This makes it so the client drivers cannot simultaneously post adminq commands. However, the completions happen in a different context, which means multiple adminq commands can be posted sequentially and all waiting on completion. On the FW side, the backing adminq request queue is only 16 entries long and the retry mechanism and/or overflow/stuck prevention is lacking.
This can cause the adminq to get stuck, so commands are no longer processed and completions are no longer sent by the FW. As an initial fix, prevent more than 16 outstanding adminq commands so there's no way to cause the adminq from getting stuck. This works because the backing adminq request queue will never have more than 16 pending adminq commands, so it will never overflow. This is done by reducing the adminq depth to 16. (CVE-2025-37987)
