CVE-2022-49727

EUVD-2022-54508
In the Linux kernel, the following vulnerability has been resolved:

ipv6: Fix signed integer overflow in l2tp_ip6_sendmsg

When len >= INT_MAX - transhdrlen, ulen = len + transhdrlen will be
overflow. To fix, we can follow what udpv6 does and subtract the
transhdrlen from the max.
