CVE-2020-8899 is a critical-severity vulnerability rated 10/10 on the CVSS scale. There is a buffer overwrite vulnerability in the Quram qmg library of Samsung's Android OS versions O(8.x), P(9.0) and Q(10.0). An unauthenticated, unauthorized attacker sending a specially crafted MMS to a vulnerable phone can trigger a heap-based buffer overflow in the Quram image codec leading to an arbitrary remote code execution (RCE) without any user interaction. EPSS estimates a 5.71% chance of exploitation in the next 30 days.
