ThreadX<6.4.0: xQueueCreate Heap Ovfl in FreeRTOS API
CVE-2024-2212 Published on March 26, 2024
Integer wraparounds, under-allocations, and heap buffer overflows in Eclipse ThreadX xQueueCreate() and xQueueCreateSet()
In Eclipse ThreadX before 6.4.0, xQueueCreate() and xQueueCreateSet()
functions from the FreeRTOS compatibility API
(utility/rtos_compatibility_layers/FreeRTOS/tx_freertos.c) were missing
parameter checks. This could lead to integer wraparound,
under-allocations and heap buffer overflows.
Vulnerability Analysis
CVE-2024-2212 is exploitable with local system access, requires user interaction. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have a high impact on confidentiality and integrity, and a small impact on availability.
Weakness Types
Heap-based Buffer Overflow
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
Integer Overflow or Wraparound
The software performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. An integer overflow or wraparound occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may wrap to become a very small or negative number. While this may be intended behavior in circumstances that rely on wrapping, it can have security consequences if the wrap is unexpected. This is especially the case if the integer overflow can be triggered using user-supplied inputs. This becomes security-critical when the result is used to control looping, make a security decision, or determine the offset or size in behaviors such as memory allocation, copying, concatenation, etc.
