CVE-2023-52746

Low

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.
