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. • https://www.exploit-db.com/exploits/42048 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0d0e57697f162da4aa218b5feafe614fb666db07 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.11.1 http://www.securityfocus.com/bid/98635 https://bugs.chromium.org/p/project-zero/issues/detail?id=1251 https://github.com/torvalds/linux/commit/0d0e57697f162da4aa218b5feafe614fb666db07 https://source.android.com/security/bulletin/2017-09-01 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
