Vulnerability Title
ipv6: Fix use-after-free in inet6_addr_del().
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix use-after-free in inet6_addr_del(). syzbot reported use-after-free of inet6_ifaddr in inet6_addr_del(). [0] The cited commit accidentally moved ipv6_del_addr() for mngtmpaddr before reading its ifp->flags for temporary addresses in inet6_addr_del(). Let's move ipv6_del_addr() down to fix the UAF.
