Ponteiro não inicializado

Ocorre quando um ponteiro é usado sem ter recebido um endereço de memória válido antes. O código tenta acessar ou modificar dados através de um ponteiro que aponta para uma posição arbitrária ou lixo de memória, causando comportamento impredizível, corrupção de dados ou crash.

Example

Uma função aloca memória para uma estrutura, mas em um caminho de execução esquece de inicializar um ponteiro dentro dela. Quando outra parte do código tenta usar esse ponteiro, ele aponta para lixo de memória, causando leitura ou escrita em endereços inválidos.

How to mitigate

Sempre inicialize ponteiros explicitamente no ponto de declaração (com NULL ou um endereço válido) e valide antes de usar. Use ferramentas de análise estática (Clang Static Analyzer, Valgrind) e, em linguagens modernas, prefira gerenciamento automático de memória ou smart pointers ao invés de ponteiros brutos.
