Here's the scope of it
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.
