Versions prior to and including 4.8 are vulnerable to an out-of-bounds write that can occur in the BLE-L2CAP module. The Bluetooth Low Energy - Logical Link Control and Adaptation Layer Protocol (BLE-L2CAP) module handles fragmentation of packets up the configured MTU size. When fragments are reassembled, they are stored in a packet buffer of a configurable size, but there is no check to verify that the packet buffer is large enough to hold the reassembled packet. In Contiki-NG's default configuration, it is possible that an out-of-bounds write of up to 1152 bytes occurs. The vulnerability has been patched in the \"develop\" branch of Contiki-NG, and will be included in release 4.9. The problem can be fixed by applying the patch in Contiki-NG pull request #2254 prior to the release of version 4.9.\n\ud83d\udccf Published: 2023-01-25T06:15:34.128Z\n\ud83d\udccf Modified: 2025-03-11T13:32:09.104Z\n\ud83d\udd17 References:\n1. https://github.com/contiki-ng/contiki-ng/security/advisories/GHSA-qr4q-6h3m-h3g7\n2. https://github.com/contiki-ng/contiki-ng/pull/2254", "creation_timestamp": "2025-03-11T13:39:45.000000Z"}
