How to fix?

There is no fixed version for Centos:7 kernel-tools.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-tools package and not the kernel-tools package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

bpf: fix overflow check in adjust_jmp_off()

adjust_jmp_off() incorrectly used the insn->imm field for all overflow check, which is incorrect as that should only be done or the BPF_JMP32 | BPF_JA case, not the general jump instruction case. Fix it by using insn->off for overflow check in the general case.
