* kernel: tun: bugs for oversize packet when napi frags enabled in tun_napi_alloc_frags (CVE-2023-3812)

* kernel: use after free in nvmet_tcp_free_crypto in NVMe (CVE-2023-5178)

* kernel: use-after-free due to race condition occurring in dvb_register_device() (CVE-2022-45884)

* kernel: use-after-free due to race condition occurring in dvb_net.c (CVE-2022-45886)

* kernel: use-after-free due to race condition occurring in dvb_ca_en50221.c (CVE-2022-45919)
