Description
Description
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).
