Bug Description

The adjust_branches function in kernel/bpf/verifier.c in the Linux kernel before 4.5 does not consider the delta in the backward-jump case, which allows local users to obtain sensitive information from kernel memory by creating a packet filter and then loading crafted BPF instructions.

Break-Fix: 9bac3d6d548e5cc925570b263f35b70a00a00ffd a1b14d27ed0965838350f1377ff97c93ee383492
