Uso de recurso não inicializado

O código utiliza uma variável, buffer, ponteiro ou outro recurso sem atribuir um valor inicial válido. Isso causa comportamento imprevisível: o programa lê lixo de memória ou executa operações com dados aleatórios, podendo levar a falhas, vazamento de informação ou execução de código arbitrário.

Ejemplo

Um desenvolvedor declara um array local sem zerá-lo e o passa diretamente para uma função criptográfica; a função processa dados lixo da stack anterior, compromentendo a segurança da operação criptográfica. Ou um ponteiro é usado antes de ser alocado, causando acesso a endereço de memória inválido.

Cómo mitigar

Inicialize sempre variáveis no ponto de declaração (em C/C++: use memset, calloc ou atribua valores válidos; em linguagens gerenciadas, confie no runtime). Use analisadores estáticos (como Clang Static Analyzer ou Coverity) para detectar leitura sem inicialização; implemente code review obrigatório para declarações de recursos.
