Uso após liberação de memória

Ocorre quando o código tenta acessar um bloco de memória que já foi desalocado (free/delete). O ponteiro continua apontando para aquele endereço, mas o dado ali pode ter sido sobrescrito por outra operação, causando comportamento impredizível, corrupção de dados ou execução de código arbitrário.

Example

Um buffer é alocado, depois liberado com free(). Mais adiante, o código ainda tenta ler ou escrever naquele mesmo ponteiro sem verificar. Se um atacante controlar a alocação subsequente daquele endereço, consegue manipular o conteúdo que será lido.

How to mitigate

Anule o ponteiro imediatamente após liberar (ptr = NULL), implemente análise estática para detectar acessos pós-liberação, use ferramentas como valgrind ou AddressSanitizer nos testes, e considere linguagens com gerenciamento automático de memória para código sensível.
