Insufficient option length validation in the IPv6 Router Advertisement parser in FreeRTOS-Plus-TCP before V4.2.6 and V4.4.1 allows an adjacent network actor to cause a denial of service (device crash) by sending a crafted Router Advertisement with a truncated PREFIX_INFORMATION option that is smaller than the expected structure size. To mitigate this issue, users should upgrade to the fixed version when available.
