Name of the Vulnerable Software and Affected Versions NXP MQX versions 5.1 and prior

Description The issue is related to integer overflow in mem alloc, lwmem alloc, and partition functions. This can lead to unverified memory assignment, resulting in arbitrary memory allocation and unexpected behavior, such as a crash or remote code injection/execution.

Recommendations For NXP MQX versions 5.1 and prior, consider restricting the use of the mem alloc, lwmem alloc, and partition functions until a patch is available.
