CVE-2020-0367
📋 TL;DR
CVE-2020-0367 is an out-of-bounds write vulnerability in Android System-on-Chip (SoC) components that could allow attackers to execute arbitrary code or cause denial of service. This affects Android devices using vulnerable SoC implementations. The vulnerability stems from missing bounds checks in memory operations.
💻 Affected Systems
- Android devices with vulnerable SoC implementations
📦 What is this software?
Android by Google
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete device compromise, data theft, or persistent backdoor installation.
Likely Case
Local privilege escalation allowing apps to gain elevated permissions or cause system crashes.
If Mitigated
Limited impact with proper app sandboxing and SELinux policies preventing privilege escalation.
🎯 Exploit Status
Exploitation requires local access or malicious app installation; no public exploit code available.
