Description
In the Linux kernel, the following vulnerability has been resolved: net/nfc/rawsock.c: fix a permission check bug The function rawsock_create() calls a privileged function sk_alloc(), which requires a ns-aware check to check net->user_ns, i.e., ns_capable(). However, the original code checks the init_user_ns using capable(). So we replace the capable() with ns_capable().
