一、漏洞信息
漏洞编号:CVE-2024-26874
漏洞归属组件:kernel
漏洞归属的版本:4.19.140,4.19.194,4.19.90,5.10.0,6.1.0,6.1.14,6.1.19,6.1.5,6.1.6,6.1.8,6.4.0
CVSS V2.0分值:
BaseScore:0.0 Low
Vector:CVSS:2.0/
漏洞简述:
In the Linux kernel, the following vulnerability has been resolved:drm/mediatek: Fix a null pointer crash in mtk_drm_crtc_finish_page_flipIt s possible that mtk_crtc->event is NULL inmtk_drm_crtc_finish_page_flip().pending_needs_vblank value is set by mtk_crtc->event, but inmtk_drm_crtc_atomic_flush(), it s is not guarded by the samelock in mtk_drm_finish_page_flip(), thus a race condition happens.Consider the following case:CPU1 CPU2step 1:mtk_drm_crtc_atomic_begin()mtk_crtc->event is not null, step 1: mtk_drm_crtc_atomic_flush: mtk_drm_crtc_update_config( !!mtk_crtc->event)step 2:mtk_crtc_ddp_irq ->mtk_drm_finish_page_flip:lockmtk_crtc->event set to null,pending_needs_vblank set to falseunlock pending_needs_vblank set to true, step 2: mtk_crtc_ddp_irq -> mtk_drm_finish_page_flip called again, pending_needs_vblank is still true //null pointerInstead of guarding the entire mtk_drm_crtc_atomic_flush(), it s moreefficient to just check if mtk_crtc->event is null before use.
