Loop infinito com condição de saída inalcançável

O programa entra em um loop cuja condição de parada nunca é satisfeita, fazendo-o executar indefinidamente. Isso consome recursos (CPU, memória) sem progresso, causando travamento, negação de serviço ou comportamento impredizível da aplicação.

Exemplo

Um validador de entrada que loop enquanto o valor não é válido, mas nunca atualiza a variável de controle; ou uma fila de processamento que tenta desempilhar itens, mas a condição de parada verifica uma variável que nunca muda. O servidor fica preso processando eternamente.

Como mitigar

Revisão de lógica: garantir que toda variável usada na condição de saída seja modificada dentro do loop. Implementar timeouts e limites de iteração como salvaguarda. Testes com entrada válida, inválida e edge cases para detectar loops travados antes do deploy.
