Weakness (CWE)
CWE-666: Operation on Resource in Wrong Phase of Lifetime
The product performs an operation on a resource at the wrong phase of the resource's lifecycle, which can lead to unexpected behaviors.
How to prevent it (2 mitigations)
-
Architecture and Design
Follow the resource's lifecycle from creation to release.
-
Implementation
For each phase, it is important to follow the specifications outlined for how to operate on the resource and to ensure that the resource is in the expected phase. Otherwise, if a resource is in one phase but the operation is not valid for that phase (i.e., an incorrect phase of the resource's lifetime), then this can produce resultant weaknesses.

Kernel panic in the it82xx2 USB device controller driver via re-initialization of a busy delayable work item
The ITE it82xx2 USB device-controller driver initialized its bus-suspend detection work with k_work_init_delayable(&priv->suspended_work, suspended_handler) inside it82xx2_enable() (the driver's .enable op) in drivers/usb/udc/udc_it82xx2.c. This work item is …

Missing channel-state validation in Zephyr Bluetooth Classic L2CAP receive path
The Bluetooth Classic (BR/EDR) L2CAP receive handler bt_l2cap_br_recv() in subsys/bluetooth/host/classic/l2cap_br.c dispatched inbound data PDUs based only on the destination channel ID, without checking that the target channel had reached the BT_L2CAP_CONNEC…

Rust XCB `xcb::Connection::connect_to_fd*` functions violate I/O safety
The API of `xcb::Connection` has constructors which allow an arbitrary `RawFd` to be used as a socket connection. On either failure of these constructors or on the drop of `Connection`, it closes the associated file descriptor. Thus, a program which uses an `…
