Improper handling of the full-buffer case in the Zephyr Bluetooth implementation can result in memory corruption. This issue affects: zephyrproject-rtos zephyr version 2.2.0 and later versions, and version 1.14.0 and later versions.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
The product writes data past the end, or before the beginning, of the intended buffer.
