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...

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-2026-19738 Retained RX node leak and reachable assertion in Bluetooth Controller CIS Create procedures

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-2026-19738

The Bluetooth Link Layer Control Procedure (LLCP) implementation in Zephyr RTOS contains a memory leak and reachable assertion during Connected Isochronous Stream (CIS) creation. Specifically, in subsys/bluetooth/controller/ll_sw/ull_llcp_cc.c, the "invalid PDU received" paths of llcp_rp_cc_rx() ...

CVE-2026-19935

The Zephyr Bluetooth host is vulnerable to a use-after-free flaw in the L2CAP connection-oriented channel (CoC) object. When using a dynamic PSM (0x0080-0x00FF), the system queues received data for deferred processing via a k_work item. However, during channel teardown in l2cap_chan_destroy(), th...

CVE-2026-19935 Use-after-free of an L2CAP CoC channel object in the Zephyr Bluetooth host: RX work item is not cancelled on channel teardown

The Bluetooth LE host queues received L2CAP connection-oriented channel CoC data for deferred processing through a struct kwork embedded in the channel object lechan-rxwork, handler l2caprxprocess whenever the channel uses a dynamic PSM 0x0080-0x00FF. Channel teardown in l2capchandestroy in...

CVE-2026-98247

A flaw was found in the Linux kernel's Bluetooth subsystem. When processing responses for supported codecs, the parser fails to verify that adequate buffer space remains before reading the vendor codec count. A malicious or malfunctioning Bluetooth controller can supply a truncated response packe...

CVE-2026-98246

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition during Bluetooth device closure allows codec list cleanup to proceed without appropriate locking while a concurrent socket option query is reading codec entries. A local user can exploit this vulnerability to trigger a...

CVE-2026-98297

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition occurs when network transmission requests are queued while the Bluetooth device is being shut down and its background workqueue is draining. A local attacker could exploit this vulnerability by sending data through...

CVE-2026-98296

A flaw was found in the Linux kernel's Intel PCIe Bluetooth driver. The driver fails to validate the size of outgoing transmission packets before copying them into a fixed Direct Memory Access DMA buffer. A local attacker could exploit this issue by submitting oversized packets, triggering a buff...

CVE-2026-98295

A flaw was found in the Linux kernel's Bluetooth subsystem. A local user can cause a Denial of Service DoS or memory corruption by disconnecting a Bluetooth device during an active diagnostic crash dump. Because the system fails to cancel pending dump tasks upon device unregistration, background...

CVE-2026-98294

A flaw was found in the Linux kernel's Qualcomm Bluetooth driver. Under specific error-recovery conditions, unbinding the driver after a device failure causes the system to write data to an already closed serial port. A local user could trigger this condition, resulting in a null-pointer...
