CVE-2026-15460 Missing channel-state validation in Zephyr Bluetooth Classic L2CAP receive path

The Bluetooth Classic BR/EDR L2CAP receive handler btl2capbrrecv in subsys/bluetooth/host/classic/l2capbr.c dispatched inbound data PDUs based only on the destination channel ID, without checking that the target channel had reached the BTL2CAPCONNECTED state. A dynamic channel is assigned its RX...

kernel: Bluetooth: l2cap: Add missing chan lock in l2cap_ecred_reconf_rsp

A flaw was found in the Linux kernel's Bluetooth Logical Link Control and Adaptation Protocol L2CAP implementation. A remote Bluetooth Low Energy BLE device can exploit this by sending a specially crafted L2CAP ECRED reconfiguration response. This can lead to the corruption of the channel list,...
