CVE-2022-49014

CVE-2022-49014 affects the Linux kernel net/tun subsystem. A use-after-free occurs in tun_detach() when sock_put() drops the last reference to struct net before net notifier code (notifier_call_chain/netdev_state_change) has finished accessing it. The patch fixes this by calling sock_put() from t...
