Details

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Fix a null pointer crash in mtkdrmcrtcfinishpageflip It's possible that mtkcrtc->event is NULL in mtkdrmcrtcfinishpageflip(). pendingneedsvblank value is set by mtkcrtc->event, but in mtkdrmcrtcatomicflush(), it's is not guarded by the same lock in mtkdrmfinishpageflip(), thus a race condition happens. Consider the following case: CPU1 CPU2 step 1: mtkdrmcrtcatomicbegin() mtkcrtc->event is not null, step 1: mtkdrmcrtcatomicflush: mtkdrmcrtcupdateconfig( !!mtkcrtc->event) step 2: mtkcrtcddpirq -> mtkdrmfinishpageflip: lock mtkcrtc->event set to null, pendingneedsvblank set to false unlock pendingneedsvblank set to true, step 2: mtkcrtcddpirq -> mtkdrmfinishpageflip called again, pendingneedsvblank is still true //null pointer Instead of guarding the entire mtkdrmcrtcatomicflush(), it's more efficient to just check if mtkcrtc->event is null before use.
