Uso após liberação de memória

Ocorre quando o código tenta acessar uma área de memória que já foi liberada (deallocated). O programa continua usando um ponteiro que aponta para um endereço inválido, causando leitura/escrita em memória não controlada. Isso pode levar a crash, corrupção de dados ou execução arbitrária de código.

Ejemplo

Um navegador aloca memória para um objeto DOM, depois o remove da página e libera a memória. Se um script JavaScript ainda tentar acessar esse objeto deletado, o navegador tenta ler/escrever em um endereço que agora contém outro dado, causando comportamento impredizível ou exploração por atacante.

Cómo mitigar

Use linguagens com garbage collection (Java, Python, C#) ou práticas rigorosas: null os ponteiros após free(), use smart pointers (C++), evite compartilhamento de referências sem sincronização, faça testes de memória com ferramentas como Valgrind ou AddressSanitizer.
