Improper Restriction of Operations within the Bounds of a Memory Buffer and Stack-based Buffer Overflow vulnerabilities were discovered in Apache NuttX RTOS Bluetooth Stack (HCI and UART components) that may result in system crash, denial of service, or arbitrary code execution, after receiving maliciously crafted packets.

The issue is related to insufficient protection against local privilege escalation via Return Oriented Programming techniques, should a vulnerability exist that allows code injection and execution. This affects ARMv7-M MPU ports and ARMv8-M ports with Memory Protected Unit (MPU) support enabled, i.e., `configENABLE MPU` set to 1.
