NVD Vulnerability Detail

CVE-2017-9150

Summary	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.

JVN Vulnerability Information

Linux Kernel の kernel/bpf/verifier.c の do_check 関数における重要なアドレス情報を取得される脆弱性

Title	Linux Kernel の kernel/bpf/verifier.c の do_check 関数における重要なアドレス情報を取得される脆弱性
Summary	Linux Kernel の kernel/bpf/verifier.c の do_check 関数は、print_bpf_insn 関数の出力制限に対して allow_ptr_leaks の値を有効にしないため、重要なアドレス情報を取得される脆弱性が存在します。
Possible impacts	ローカルユーザにより、巧妙に細工された bpf システムコールを介して、重要なアドレス情報を取得される可能性があります。
Solution	ベンダより正式な対策が公開されています。ベンダ情報を参照して適切な対策を実施してください。
