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."}],"source":{"advisory":"GHSA-qr4q-6h3m-h3g7","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T10:35:33.614Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/contiki-ng/contiki-ng/security/advisories/GHSA-qr4q-6h3m-h3g7","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/contiki-ng/contiki-ng/security/advisories/GHSA-qr4q-6h3m-h3g7"},{"name":"https://github.com/contiki-ng/contiki-ng/pull/2254","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/contiki-ng/contiki-ng/pull/2254"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-03-11T13:31:56.295086Z","id":"CVE-2023-23609","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-03-11T13:32:09.104Z"}}]}}
