CVE-2023-52746

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

xfrm/compat: prevent potential spectre v1 gadget in xfrm_xlate32_attr()

  int type = nla_type(nla);

  if (type > XFRMA_MAX) {
            return -EOPNOTSUPP;
  }

@type is then used as an array index and can be used
as a Spectre v1 gadget.

  if (nla_len(nla) < compat_policy[type].len) {

array_index_nospec() can be used to prevent leaking
content of kernel memory to malicious users.
