CVE-2026-19935

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-2026-19935 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-2026-19935

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-2026-97977

The Linux kernel contains a Use-After-Free (UAF) vulnerability in the btusb Bluetooth driver. The issue occurs because btusb_close() and btusb_flush() use the asynchronous cancel_delayed_work() function; if btusb_rx_work() is already executing on another CPU, it continues running after the cancel...
