Descriptions

The do_check function in kernel/bpf/verifier.c in the Linux kernel before 4.11.1 does not make the allow_ptr_leaks value available for restricting the output of the print_bpf_insn function, which allows local users to obtain sensitive address information via crafted bpf system calls.

La función do_check en el archivo kernel/bpf/verifier.c en el kernel de Linux anterior a versión 4.11.1, no hace que el valor de allow_ptr_leaks esté disponible para restringir la salida de la función print_bpf_insn, que permite a los usuarios locales obtener información de una dirección confidencial por medio de llamadas del sistema bpf especialmente diseñadas.
