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-2025-37754 公告中提及的一个漏洞影响。- 已修复 Linux 内核中的下列漏洞：drm/i915/huc: Fix fence not released on early probe errors HuC delayed loading fence, introduced with commit 27536e03271da (drm/i915/huc:
track delayed HuC load with a fence), is registered with object tracker early on driver probe but unregistered only from driver remove, which is not called on early probe errors. Since its memory is allocated under devres, then released anyway, it May happen to be allocated again to the fence and reused on future driver probes, resulting in kernel warnings that taint the kernel: <4> [309.731371]
