BLE-Replay

BLE-Replay BLE-Replay is a Bluetooth Low Energy BLE peripheral assessment tool. It pulls/consumes Bluetooth HCI logs from your mobile device and extracts all of the writes that the central makes to a peripheral. This data can be replayed using most Bluetooth dongles from a Linux host, or saved to...

CVE-2026-79982

The Bluetooth HCI USB transport class of the new USB device stack, subsys/usb/devicenext/class/bthci.c, copies every controller-to-host HCI packet into a USB transfer buffer before enqueuing it on an endpoint. bthcitxsyncin allocated that buffer from bthcieppool, a fixed pool whose slots are only...

CVE-2026-79982

The Bluetooth HCI USB transport class in subsys/usb/device_next/class/bt_hci.c contains an out-of-bounds write vulnerability. The bt_hci_tx_sync_in() function allocates a buffer from bt_hci_ep_pool (fixed at 64 bytes on full-speed-only builds) and uses net_buf_add_mem() to copy controller-to-host...

CVE-2026-79982 Out-of-bounds write in the USB Bluetooth HCI transport class when a controller-to-host HCI packet exceeds the bulk endpoint maximum packet size

The Bluetooth HCI USB transport class of the new USB device stack, subsys/usb/devicenext/class/bthci.c, copies every controller-to-host HCI packet into a USB transfer buffer before enqueuing it on an endpoint. bthcitxsyncin allocated that buffer from bthcieppool, a fixed pool whose slots are only...

CVE-2026-98461

A flaw was found in the Linux kernel's Bluetooth subsystem. This vulnerability can lead to a Denial of Service DoS due to an out-of-bounds memory read. The issue occurs when the Host Controller Interface HCI socket implementation filters event packets without verifying that the packet buffer is...

CVE-2026-98460

A flaw was found in the Linux kernel's Bluetooth subsystem. This flaw allows a local, unprivileged user to bypass security restrictions and send unauthorized commands directly to the Bluetooth hardware. The vulnerability exists because the Host Controller Interface HCI raw socket improperly filte...
