Value Overflow Bug
A critical bug where arithmetic overflow creates or destroys coins unintentionally.
Overflow or underflow in consensus code can mint excess coins or break supply invariants. Bitcoin fixed a historical overflow in 2010 that created trillions of coins in a single transaction before being rolled back.
"Nodes patched and coordinated a chain rollback to invalidate the overflow transaction and restore the correct total supply."
