CVE-2026-7425
Last modified
CVE-2026-7425 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
