patch2 View in context:
https://bugs.webkit.org/attachment.cgi?id=151075&action=review
> Source/WebCore/platform/graphics/filters/arm/NEONHelpers.h:40 > - uint32x2_t temporary1 = vset_lane_u32(*source, temporary1, 0); > + uint32x2_t temporary1 = vld1_u32(source);
I think vld1_u32 reads a whole register, which can lead to buffer overflow.
