Ponteiro não inicializado

Ocorre quando um ponteiro é declarado mas nunca recebe um endereço de memória válido antes de ser dereferenciado (acessado). O código tenta ler ou escrever em um endereço aleatório da memória, causando comportamento imprevisível: crash, corrupção de dados ou execução de código arbitrário.

Ejemplo

Um desenvolvedora declara `int *ptr;` em C, depois tenta acessar `*ptr = 42;` sem antes fazer `ptr = malloc(sizeof(int))` ou `ptr = &alguma_variavel;`. O programa escreve em um endereço lixo, quebrando algo na memória ou disparando uma violação de segmentação.

Cómo mitigar

Sempre inicialize ponteiros antes de usar: atribua um endereço válido (alocação dinâmica, referência a variável, ou NULL) no mesmo ponto da declaração. Use ferramentas estáticas (clang-analyzer, valgrind) para detectar casos antes do runtime. Em C++/Rust, prefira smart pointers ou referências, que forçam inicialização.
