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,...

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: cancel pendingrxwork before taking conn-lock l2capconndel takes conn-lock and then calls cancelworksync for pendingrxwork. processpendingrx takes the same mutex, so teardown can deadlock against the worker it is...
CVE-2026-64206
Summary of CVE-2026-64206 : In the Linux kernel Bluetooth L2CAP subsystem, teardown can deadlock due to a circular lock between l2cap_conn_del() and process_pending_rx(). Specifically, l2cap_conn_del() takes conn->lock and then cancels pending_rx_work, while process_pending_rx() may contend fo...
