Vulnerability from github – Published: 2025-03-27 18:31 – Updated: 2025-10-30 18:31

Details

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.

Severity

5.5 (Medium)
