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: 修复 out_fence_ptr 错误路径中 drm_pending_vblank_event 的资源泄漏问题 当提供了 out_fence_ptr 但未设置 DRM_MODE_PAGE_FLIP_EVENT 标志时，系统会分配一个 drm_pending_vblank_event 结构体。如果后续在 setup_out_fence() 过程中发生分配失败或其他错误，该事件结构体的 base.fence 字段将不会被设置，并且无法在 complete_signal

Vulnerability Title
drm: Fix drm_pending_vblank_event leak in error path for out_fence_ptr
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: drm: Fix drm_pending_vblank_event leak in error path for out_fence_ptr When an out_fence_ptr is provided but DRM_MODE_PAGE_FLIP_EVENT is not set, a drm_pending_vblank_event will be allocated. If later, there is an allocation failure or another failure at setup_out_fence(), that event will not have base.fence set and it will not be released at complete_signaling(). Release the event and set crtc_state->event to NULL just like in the DRM_MODE_PAGE_FLIP_EVENT case when there is a failure at drm_event_reserve_init(). That is, prepare_signaling() releases the event and there is nothing to be done at complete_signaling(). Use drm_event_cancel_free() as that will also undo drm_event_reserve_init() in case it has been called.
