Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已修复以下漏洞： drm/gud：验证支持的旋转属性中是否包含 GUD_ROTATION_0 在调用 时，旋转参数被设置为 ，并将设备报告的旋转位掩码作为 参数传入。但驱动从未验证 是否存在于支持的旋转列表中，因此，若设备在其 中省略了该位，则会在 中触发 警告。 修复方法：如果设备未包含 位，则跳过旋转属性的创建。

Vulnerability Title
drm/gud: validate GUD_ROTATION_0 is present in supported rotations
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: drm/gud: validate GUD_ROTATION_0 is present in supported rotations The rotation argument to drm_plane_create_rotation_property() is set to DRM_MODE_ROTATE_0, and the device reported rotation bitmask is used as the supported_rotations argument. The driver never validates that GUD_ROTATION_0 is present, so a device that omits it from its GUD_PROPERTY_ROTATION triggers the WARN_ON(rotation & ~supported_rotations) in drm_plane_create_rotation_property() Fix this by skipping the creation of rotation property if the device doesn't have the GUD_ROTATION_0 bit
