0 CVE-2025-66647 is a buffer overflow vulnerability in the IPv6 fragmentation reassembly implementation of RIOT-OS versions prior to 2025.10. The flaw occurs because the system does not check the size when copying the first IPv6 fragment into the reassembly buffer, allowing an attacker to overflow this buffer by manipulating fragment sizes. This overflow can corrupt adjacent packet buffers, potentially enabling further memory corruption and remote code execution. Exploitation requires the vulnerable gnrc_ipv6_ext_frag module to be enabled and the ability to send arbitrary IPv6 packets to the target device. Although the CVSS score is low (1.7), the vulnerability could be critical in specific IoT contexts where RIOT-OS is deployed. The issue is fixed in version 2025.10, and no known exploits are currently reported in the wild. Join the discussion | CVE Database V5 | 12/17/2025, 20:21:13 UTC Added: 12/17/2025, 20:28:30 UTC |
