Linux Distros 未修补的漏洞：CVE-2022-50260

简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- drm/msm使 .remove 和 .shutdown HW 关机一致。驱动程序的 .remove 和 .shutdown 回调在不同的代码路径中执行。当从总线删除设备时调用前者而在系统关闭以使设备停顿时调用后者。这意味着两者之间存在某些重叠，因为两者都必须注意正确关闭硬件。但是目前这两个回调中使用的逻辑在 msm 驱动程序中不一致可能会造成内核错误。例如，在 .remove 上，组件被删除，其 .unbind 回调会导致硬件关闭，但前提是 DRM 设备已被标记为已注册。该检查在 .shutdown 逻辑中不存在，这可导致驱动程序为尚未正确初始化的 DRM 设备调用 drm_atomic_helper_shutdown()。如果预期子设备的驱动程序探测失败则可能发生此类情况因为永远不会执行 .bind 回调。如果是这种情况drm_atomic_helper_shutdown() 将尝试获取仅当在设备绑定期间调用 drm_mode_config_init() 时才初始化的互斥体。尝试在提交 623f279c7781 中修复此缺陷 drm/msm修复 GPU 组件绑定失败时的关闭挂钩但遗憾的是在某些情况下仍然会发生上述情况即 systemd-shutdown[1]正在关闭电源。 kvm退出硬件虚拟化平台 wifi-firmware.0
