Overview

About vulnerability

In the Linux kernel, the following vulnerability has been resolved:

tcp_metrics: validate source addr length

I don’t see anything checking that TCP_METRICS_ATTR_SADDR_IPV4 is at least 4 bytes long, and the policy doesn’t have an entry for this attribute at all (neither does it for IPv6 but v6 is manually validated).
