Falha no kernel do Linux permite que usuários sem privilégios obtenham acesso root

Pesquisadores da Qualys identificaram uma falha de lógica no kernel do Linux que permite que usuários locais sem privilégios revelem arquivos confidenciais e executem comandos arbitrários como root.

A vulnerabilidade afeta instalações padrão de várias das principais distribuições Linux. A Unidade de Pesquisa de Ameaças da Qualys descobriu o problema e detalhou a questão em uma postagem de blog publicada na sexta-feira.
