Summary

An issue identified in the Texas Instruments Bluetooth® stack can cause devices to stop responding properly. The potential vulnerability in the Bluetooth stack implementation fails to properly validate the MaxRxOctets parameter during the LL data length update procedure, and if an invalid value (below the lower bounds) is provided, the subsequent incoming packets in the connection are dropped silently.
