FAUCET Score

CVE-2020-0409 is an integer overflow vulnerability in the FileMap.cpp component of Android, affecting versions 8.0 through 10. This flaw can lead to an out-of-bounds write, enabling local escalation of privilege without requiring user interaction or additional execution privileges. Rated with a CVSS score of 7.8 (High), it presents a significant risk due to its low attack complexity and high impact on confidentiality, integrity, and availability. While there is no evidence of active exploitation, no public exploit code (Metasploit, Nuclei, ExploitDB), and it is not listed in CISA's KEV catalog, it has received some community discussion and media coverage, notably from BleepingComputer regarding Samsung's November 2020 patches.
