What it is

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btnxpuart: Fix skb leak in nxp_process_fw_dump()

When CONFIG_DEV_COREDUMP=n, hci_devcd_append() returns -EOPNOTSUPP

without freeing its skb argument. This leaks the cloned skb and also

prevents nxp_set_ind_reset() from being called to perform recovery.

Fix by guarding the hci_devcd_append(hdev, skb_clone(skb, GFP_ATOMIC))

call with IS_ENABLED(CONFIG_DEV_COREDUMP).
