In the Linux kernel, the following vulnerability has been resolved:
ipv4: prevent potential spectre v1 gadget in ip_metrics_convert()
if (!type) continue; if (type > RTAX_MAX) return -EINVAL; ... metrics[type - 1] = val;
@type being used as an array index, we need to prevent cpu speculation or risk leaking kernel memory content.
