Descriptions

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.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: xfrm/compat: previene el posible gadget spectre v1 en xfrm_xlate32_attr() int type = nla_type(nla); if (tipo &gt; XFRMA_MAX) { return -EOPNOTSUPP; } @type luego se usa como índice de matriz y se puede usar como un gadget Spectre v1. if (nla_len(nla) &lt; compat_policy[type].len) { array_index_nospec() se puede utilizar para evitar la filtración de contenido de la memoria del kernel a usuarios malintencionados.
