CVE-2026-19738
The Bluetooth Link Layer Control Procedure LLCP implementation for Connected Isochronous Stream CIS creation retains an RX node ctx-noderef.rx, marked NODERXTYPERETAIN so it can later be reused as the host notification — on the peripheral while awaiting the Host's reply to an LLCISREQ, and on the...
CVE-2026-19739
The Bluetooth Link Layer control procedure code in subsys/bluetooth/controller/llsw/ullllcpconnupd.c retains the received RX node while a Connection Update / Connection Parameter procedure waits for its instant, so the node can later carry the host notification llcprxnoderetain, which marks it...
CVE-2026-19739 Bluetooth LE controller leaks a retained RX node when an unexpected LL Control PDU arrives during a Connection Update
The Bluetooth Link Layer control procedure code in subsys/bluetooth/controller/llsw/ullllcpconnupd.c retains the received RX node while a Connection Update / Connection Parameter procedure waits for its instant, so the node can later carry the host notification llcprxnoderetain, which marks it...
CVE-2026-19739
The Bluetooth LE controller contains a resource leak in the Link Layer control procedure located in subsys/bluetooth/controller/ll_sw/ull_llcp_conn_upd.c. When a device receives a Connection Update or Connection Parameter procedure and subsequently receives an unexpected LL Control PDU before the...
