Description
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.
