📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full system compromise with kernel-level code execution, allowing complete device control and data exfiltration.

🟠

Likely Case

Local privilege escalation from user to kernel space, application crashes, or system instability.

🟢

If Mitigated

Contained privilege escalation with limited impact due to sandboxing or SELinux policies.

🌐 Internet-Facing: LOW (requires local access or malicious app installation)

🏢 Internal Only: MEDIUM (could be exploited via malicious apps or compromised internal users)

🎯 Exploit Status

Public PoC: ✅ No

Weaponized: UNKNOWN

Unauthenticated Exploit: ✅ No

Complexity: MEDIUM

Exploitation requires local access and knowledge of GPU memory management. No public exploits known at this time.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Qualcomm security bulletin for specific patched driver versions

Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/february-2026-bulletin.html

Restart Required: Yes

Instructions:
