That validation only enforced a lower bound (pkt_len < 3); its second clause rejects a FIFO that holds more bytes than declared and therefore never bounds large values. Because the driver configures the radio for variable packet length with PKT_LEN = 0xFF, the length byte is an over-the-air value of 0-255 that reached net_pkt_rx_alloc_with_buffer() and the subsequent SPI burst read unclamped.\nAn unauthenticated attacker within radio range can transmit a frame that presents a length byte above the IEEE 802.15.4 maximum of 127 while the chip's 128-byte RX FIFO has not overflowed, so the driver's RX_FIFO_ERROR pre-check does not fire. Reaching this state depends on RF framing and timing, since the RX thread is driven off the PKT_SYNC_RXTX signal and may sample the FIFO before a packet is complete; no pairing, authentication, or user interaction is required.\nWith the default CONFIG_NET_BUF_FIXED_DATA_SIZE and CONFIG_NET_BUF_DATA_SIZE=128, an allocation larger than one fragment is satisfied by a chain of fragments, but read_rxfifo_content() performs a single SPI burst of pkt_len bytes into the first fragment's buf->data and then calls net_buf_add() with the same length. A length above 128 therefore writes up to 127 bytes past the end of a fragment in the contiguous rx_bufs pool and leaves a net_buf whose len exceeds its capacity. The overflowing bytes are FIFO-underflow output rather than attacker-chosen data, so the practical impact is network-buffer-pool corruption and crashes rather than a controlled write. Only builds that enable CONFIG_IEEE802154_CC1200 with an attached CC1200 radio are affected.\nhttps://www.cve.org/CVERecord?id=CVE-2026-75084https://github.com/zephyrproject-rtos/zephyr/commit/26a8b8294bf28523c7aa2f15cf728517980ee593https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-pgg5-wwxw-vmj8#zephyrproject #zephyr#CVE_2026_75084#bot", "url": "https://infosec.exchange/users/cve/statuses/117441572309716257"}, {"timestamp": "2026-10-16T15:24:20.665Z", "date_only": false, "value": "2026-10-16T15:24:20.665016Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-75084", "field": "containers.adp.0.metrics.0.other.content.timestamp"}, {"timestamp": "2026-10-16T15:24:20.665Z", "date_only": false, "value": "2026-10-16T15:24:20.665016Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-75084", "record": "FKIE_CVE-2026-75084", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2026-10-16T15:31:46.056Z", "date_only": false, "value": "2026-10-16T15:31:46.056Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2026-75084", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2026-10-16T15:31:46.056Z", "date_only": false, "value": "2026-10-16T15:31:46.056Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2026-75084", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-10-16T16:21:02.250Z", "date_only": false, "value": "2026-10-16T16:21:02.250", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-75084", "record": "FKIE_CVE-2026-75084", "field": "lastModified"}]}
