Descriptions
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.
A vulnerability was found in the Linux kernel's `ip_metrics_convert()` function, where improper handling of user input can potentially leak kernel memory via side channels. This issue is caused by the use of `@type`, a user-controlled input, which is an array within this function. If a CPU speculatively executes instructions past the conditional branch before the branch condition is resolved, the line `metrics[type - 1] = val` may be evaluated. A situation where `type` is out-of-bounds could lead to improper kernel memory access.
