CVE-2024-20145
📋 TL;DR
This vulnerability in V6 DA allows local privilege escalation through an out-of-bounds write due to missing bounds checks. An attacker with physical access can exploit this without additional privileges, though user interaction is required. Affects devices using MediaTek's V6 DA component.

⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with root/admin privileges, allowing complete control over the device and potential data exfiltration.
Likely Case
Local privilege escalation to gain elevated permissions on the device, enabling further malicious activities.
If Mitigated
Limited impact if physical access controls prevent unauthorized device handling and user interaction is restricted.
🎯 Exploit Status
Exploitation requires physical access and user interaction, making it less likely for widespread attacks but still a concern in targeted scenarios.
🛠️ Fix & Mitigation
✅ Official Fix
