Steffen Klassert d90c902449 af_key: Fix slab-out-of-bounds in pfkey_compile_policy. The sadb_x_sec_len is stored in the unit 'byte divided by eight'. So we have to multiply this value by eight before we can do size checks. Otherwise we may get a slab-out-of-bounds when we memcpy the user sec_ctx. Fixes: `df71837d50` ("[LSM-IPSec]: Security association restriction.")

So we have to multiply this value by eight before we can do
size checks. Otherwise we may get a slab-out-of-bounds when
