Ponteiro não inicializado

Ocorre quando um código usa um ponteiro sem antes atribuir um endereço válido a ele, fazendo com que ele aponte para lixo de memória. Isso permite leitura ou escrita em áreas arbitrárias, causando crashes, vazamento de dados ou execução de código malicioso.

Exemplo

Um driver de kernel aloca uma estrutura dinamicamente, mas em certos caminhos de código pula a inicialização do campo ponteiro que deveria referenciar um buffer. Quando outra função desreferencia esse ponteiro, acessa memória inválida e pode causar privilege escalation.

Como mitigar

Sempre inicialize ponteiros no ponto de declaração (preferencialmente com NULL) ou logo após alocação. Use ferramentas de análise estática (scan de código) e inicializadores de memória em testes para detectar uso de ponteiros soltos antes de código chegar à produção.
