CVE-2024-27226
📋 TL;DR
This vulnerability allows local privilege escalation on affected Android Pixel devices through an out-of-bounds write in the tmu_config_gov_params function. Attackers can gain elevated privileges without user interaction or additional execution permissions. Only Pixel devices running vulnerable Android versions are affected.
💻 Affected Systems
- Google Pixel devices
📦 What is this software?
Android by Google
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise allowing attackers to gain root/system-level access, install persistent malware, access all user data, and bypass security controls.
Likely Case
Local privilege escalation allowing attackers to bypass app sandboxing, access sensitive system resources, and potentially install malicious apps with elevated permissions.
If Mitigated
Limited impact with proper patch management and security controls, though unpatched devices remain vulnerable to local attacks.
🎯 Exploit Status
Exploitation requires local access but no user interaction. The vulnerability is in kernel-level code, making exploitation more complex than user-space vulnerabilities.
