Worst Case
Nearby attackers could intercept or inject content into Auracast broadcasts, potentially eavesdropping on audio streams or broadcasting malicious content to connected devices.
Likely Case
Attackers in close proximity could join Auracast sessions without authorization, accessing broadcast audio content intended for specific recipients.
If Mitigated
With proper physical security controls and updated devices, the attack surface is significantly reduced as attackers need physical proximity.
🎯 Exploit Status
Exploitation requires physical proximity to the target device. No authentication is needed to join the broadcast once the vulnerability is exploited.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: SMR Mar-2025 Release 1
