Nome do Software Vulnerável e Versões Afetadas Linux kernel versões anteriores a 7.0.11-1.1

Descrição Um problema de double free (liberação dupla de memória) existe no kernel do Linux dentro da função ice sf eth activate(). Quando auxiliary device add() falha, a execução salta para aux dev uninit e chama auxiliary device uninit(&sf dev->adev). O callback de liberação do dispositivo ice sf dev release() libera sf dev, mas o caminho de erro continua para sf dev free, que chama kfree(sf dev) novamente.

Recomendações Atualize para a versão 7.0.11-1.1 ou posterior.
