CVE-2026-7422

CVE-2026-7422 affects FreeRTOS-Plus-TCP; insufficient packet validation in IPv4/IPv6 processing (before V4.2.6 and V4.4.1) allows an adjacent attacker to bypass checksum and minimum-size checks by spoofing the Ethernet source MAC to a local endpoint, since loopback-detection skips validation for ...

CVE-2026-7422 MAC Address Validation Bypass in FreeRTOS-Plus-TCP IPv4 and IPv6 Packet Processing

Insufficient packet validation in FreeRTOS-Plus-TCP before V4.2.6 and V4.4.1 allows an adjacent network actor to bypass all checksum and minimum-size validation by spoofing the Ethernet source MAC address to match one of the device's own registered endpoints, because the loopback detection...
