Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.5

Description The issue allows local users to obtain sensitive information from kernel memory by creating a packet filter and then loading crafted BPF instructions. This is due to the adjust branches function in kernel/bpf/verifier.c not considering the delta in the backward-jump case.

Recommendations For Linux kernel versions prior to 4.5, update to version 4.5 or later to resolve the issue.
