Descriptions
An issue was discovered in the Linux kernel before 5.0.19. There is an out-of-bounds array access in __xfrm_policy_unlink, which will cause denial of service, because verify_newpolicy_info in net/xfrm/xfrm_user.c mishandles directory validation.
Se descubrió un fallo en el núcleo de Linux en versiones anteriores a 5.0.19. Hay un acceso a array fuera de límites en __xfrm_policy_unlink, lo que causará una denegación del servicio, ya que verify_newpolicy_info en net/xfrm/xfrm_user.c gestiona mal la validación de directorios.
A flaw was found in the Linux kernel. When xfrm policy removal occurs a system crash could occur. These policy changes generally occur through the ip command or a netlink socket.
