Ubuntu.comUB:CVE-2021-47285CVE-2021-47285
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().
