Vulnerability Title
N/A
Vulnerability Description
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.

Linux kernel 安全漏洞
Vulnerability Description
Linux kernel是美国Linux基金会发布的开源操作系统Linux所使用的内核。 Linux kernel 4.11.1之前的版本中的kernel/bpf/verifier.c文件的‘do_check’函数存在安全漏洞，该漏洞源于程序没有生成可用的allow_ptr_leaks值来限制‘print_bpf_insn’函数的输出。本地攻击者可借助特制的bpf系统调用利用该漏洞获取敏感的地址信息。
