CVE-2026-7426 in FreeRTOS-Plus-TCP
요약
\~에 의해 MITRE • 2026. 04. 29.
Insufficient validation of the prefix length field in IPv6 Router Advertisement processing in FreeRTOS-Plus-TCP before V4.2.6 and V4.4.1 allows an adjacent network actor to cause memory corruption by sending a crafted Router Advertisement with a prefix length value exceeding the maximum valid length, resulting in a heap buffer overflow. Users processing IPv4 RA only are not impacted.
To mitigate this issue, users should upgrade to the fixed version when available.
