5.5
MEDIUM · CVSS 3.0 · EPSS 1.3% (pctl 69)
Patch early
A public exploit exists.
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.
