33
FAUCET Score

CVE-2020-8899 is a critical buffer overflow vulnerability in the Quram qmg library affecting Samsung Android OS versions 8.x, 9.0, and 10.0. An unauthenticated attacker can achieve arbitrary remote code execution by sending a specially crafted MMS, requiring no user interaction. With a CVSS score of 9.8 (Critical) and a FAUCET Risk Score of 92/100, this vulnerability presents a significant risk due to its network-based attack vector and complete compromise potential. While no public exploits, Metasploit modules, or active exploitation are reported, its high EPSS score suggests a non-negligible probability of future exploitation.
