📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete disruption of WiFi connectivity on affected systems, requiring system restart to recover network functionality.
Likely Case
Intermittent WiFi disconnections or degraded wireless performance for targeted devices.
If Mitigated
Minimal impact if patched or if network segmentation prevents adjacent access.
🎯 Exploit Status
Race conditions require precise timing and adjacent network access, making exploitation moderately complex.
