RIOT Vulnerable to Multiple Out-of-Bounds Read When Processing Received 6LoWPAN SFR Fragments
Summary
RIOT Vulnerable to Multiple Out-of-Bounds Read When Processing Received 6LoWPAN SFR Fragments
Original description
The description as published by the source.
RIOT is an open-source microcontroller operating system, designed to match the requirements of Internet of Things (IoT) devices and other embedded devices. In version 2025.10 and prior, multiple out-of-bounds read allow any unauthenticated user, with ability to send or manipulate input packets, to read adjacent memory locations, or crash a vulnerable device running the 6LoWPAN stack. The received packet is cast into a sixlowpan_sfr_rfrag_t struct and dereferenced without validating the packet is large enough to contain the struct object. At time of publication, no known patch exists.
