Changes between FreeRTOS V10.4.6 and TBD
Changes between FreeRTOS V10.4.6 and FreeRTOS V10.5.0 released September 16 2022

+ ARMv7-M and ARMv8-M MPU ports: It is possible for a third party that
already independently gained the ability to execute injected code to
read from or write to arbitrary addresses by passing a negative argument
as the xIndex parameter to pvTaskGetThreadLocalStoragePointer() or
vTaskSetThreadLocalStoragePointer respectively.
We thank Certibit Consulting, LLC for reporting this issue.
+ ARMv7-M and ARMv8-M MPU ports: It is possible for an unprivileged task to
invoke any function with privilege by passing it as a parameter to
MPU_xTaskCreate, MPU_xTaskCreateStatic, MPU_xTimerCreate,
MPU_xTimerCreateStatic, or MPU_xTimerPendFunctionCall.
We thank Huazhong University of Science and Technology for reporting this issue.
+ ARMv7-M and ARMv8-M MPU ports: It is possible for a third party that has
already independently gained the ability to execute injected code to
achieve further privilege escalation by branching directly inside a
FreeRTOS MPU API wrapper function with a manually crafted stack frame.
We thank Certibit Consulting, LLC, Huazhong University of Science and
Technology and the SecLab team at Northeastern University for reporting
this issue.
+ ARMv7-M MPU ports: It is possible to configure overlapping memory
protection unit (MPU) regions such that an unprivileged task can access
privileged data.
We thank the SecLab team at Northeastern University for reporting this issue.
+ Add support for ARM Cortex-M55.
+ Add support for ARM Cortex-M85. Contributed by @gbrtth.
+ Add vectored mode interrupt support to the RISC-V port.
+ Add support for RV32E extension (Embedded Profile) in RISC-V GCC port.
Contributed by @Limoto.
+ Heap improvements:
- Add a check to heap_2 to track if a memory block is allocated to
the application or not. The MSB of the size field is used for this

vPortFree() is automatically cleared to zero.
- Add a new API pvPortCalloc to heap_2, heap_4 and heap_5 which has the same
signature as the standard library calloc function.
- Update the pointer types to portPOINTER_SIZE_TYPE. Contributed by
@Octaviarius.
+ Add the ability to override send and receive completed callbacks for each
instance of a stream buffer or message buffer. Earlier there could be
one send and one receive callback for all instances of stream and message

sbSEND_COMPLETED() and sbRECEIVE_COMPLETED() macros are invoked. To maintain
backwards compatibility, configUSE_SB_COMPLETED_CALLBACK defaults to 0. The
functionality is currently not supported for MPU enabled ports.
+ Generalize the FreeRTOS's Thread Local Storage (TLS) support so that it
is not tied to newlib and can be used with other c-runtime libraries also.
The default behavior for newlib support is kept same for backward
compatibility.
+ Add support to build and link FreeRTOS using CMake build system. Contributed
by @yhsb2k.
+ Add support to generate Software Bill of Materials (SBOM) for every release.
