CVE-2021-27421

Name of the Vulnerable Software and Affected Versions NXP MCUXpresso SDK versions prior to 2.8.2

Description The issue is related to an integer overflow in the SDK Malloc function. This could allow access to memory locations outside the bounds of a specified array, leading to unexpected behavior such as a segmentation fault when assigning a particular block of memory from the heap via malloc.

Recommendations For NXP MCUXpresso SDK versions prior to 2.8.2, update to version 2.8.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of the SDK Malloc function to minimize the risk of exploitation.
