A National Institute of Standards and Technology (NIST) advisory on the bug describes it as "an issue [that] was discovered in the m2m scaler driver in Samsung Mobile Processor and Wearable Processor Exynos 9820, 9825, 980, 990, 850, and W920." A use-after-free bug in the mobile processor ultimately leads to privilege escalation, the agency added.
Pixel phones can have hardware quality issues. Samsung arguably makes the best hardware. Their cameras and screens have always been way ahead of every other phone.
