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

powerpc64/bpf: Limit ldbrx to processors compliant with ISA v2.06

Johan reported the below crash with test_bpf on ppc64 e5500:

Illegal instruction

The illegal instruction turned out to be ldbrx emitted for BPF_FROM_[L|B]E, which was only introduced in ISA v2.06. Guard use of the same and implement an alternative approach for older processors.
