  - nfc: nci: free rx_data_reassembly skb on NCI device cleanup rx_data_reassembly skb is stored during NCI
    data exchange for processing fragmented packets. It is dropped only when the last fragment is processed or
    when an NTF packet with NCI_OP_RF_DEACTIVATE_NTF opcode is received. However, the NCI device may be
    deallocated before that which leads to skb leak. As by design the rx_data_reassembly skb is bound to the
    NCI device and nothing prevents the device to be freed before the skb is processed in some way and
    cleaned, free it on the NCI device cleanup. Found by Linux Verification Center (linuxtesting.org) with
    Syzkaller. (CVE-2024-26825)

Note that Nessus relies on the presence of the package as reported by the vendor.");
