Descriptions
The adjust_branches function in kernel/bpf/verifier.c in the Linux kernel before 4.5 does not consider the delta in the backward-jump case, which allows local users to obtain sensitive information from kernel memory by creating a packet filter and then loading crafted BPF instructions.
La función adjust_branches en kernel/bpf/verifier.c en el kernel de Linux en versiones anteriores a 4.5 no tiene en cuenta el delta en el caso de salto de retroceso, lo que permite a usuarios locales obtener información sensible del kernel de memoria creando un filtro de paquetes y posteriormente cargando instrucciones BPF manipuladas.
