Good morning,
You have said a
small holes/voids on the frame, it is not clear from the photos if you are showing us actual holes or just a dark area where the paint is pealing off.
A hole would say to me don't ride, whereas a paint fault would say either return or accept a partial refund for a minor defect depending upon your view of the world and how much you need the bike.
Cube frame warranties are; For all frames and rigid forks from model year 2012 we guarantee from the date of sale from the dealer:
Aluminium 6 Years Guarantee
Carbon, Alu-Carbon 3 Years Guarantee

Although other makers do offer lifetime warranties in practice they are frequently no different to 6/3 years, very few frames fail after these time periods
from defects in materials and manufacture, failure will nearly always be
wear & tear or accident.
I can't find it now but one manufacturer actually stated in their blurb something like
this frame won't last as long as our other frames because we made it light.
Understandably no maker want to commit to a miles/age limit for their frames, so even frames that the makers expect to have a limited lifespan, say 5-10 years of normal usage are often bought with the belief that they could last 60-70 years.
When they fail within the expected life time the customer is unhappy, but the truth about frame life is like politicians who tell the truth we say we want them, until we get them. The market isn't ready for an honest maker saying we can cut 500g off the frame weight at the cost of reducing the frame life down to 3 year/50,000 miles
Cube seems to have gone for 115kg for their road range and if you look at the Specialized Allez, it has weight limits of 125kg for all but the top of the range model which has 109kg, so Specialised are sort of acknowledging a weight/lifespan trade off for the Comp model.
