net: heap overflow in __audit_sockaddr()
[ Upstream commit 1661bf364ae9c506bc8795fef70d1532931be1e8 ]
We need to cap ->msg_namelen or it leads to a buffer overflow when we
to the memcpy() in __audit_sockaddr(). It requires CAP_AUDIT_CONTROL to
exploit this bug.
The call tree is:
___sys_recvmsg()
move_addr_to_user()
audit_sockaddr()
__audit_sockaddr()
