Summary
bpf: fix overflow check in adjust_jmp_off()
Details

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

bpf: fix overflow check in adjustjmpoff()

adjustjmpoff() incorrectly used the insn->imm field for all overflow check, which is incorrect as that should only be done or the BPFJMP32 | BPFJA case, not the general jump instruction case. Fix it by using insn->off for overflow check in the general case.
