An issue identified in the Texas Instruments Bluetooth® stack causes a Denial of Service (DoS) condition. The potential vulnerability can be exploited by sending a crafted LL_Pause_Enc_Req packet during the Bluetooth LE connection establishment phase. When processed by an affected device, this malformed packet can cause the device to enter an unresponsive state, requiring a manual reset to restore normal operation.
