CVE-2017-9150

Published: 22 May 2017

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.

From the Ubuntu Security Team

Jann Horn discovered that bpf in Linux kernel does not restrict the output of the print_bpf_insn function. A local attacker could use this to obtain sensitive address information.
