Description
A vulnerability in the Linux kernel's eth nfp driver caused a mismatch between the count of flow steering rules and the actual list of rules when reprogramming fails. This could lead to userspace buffer sizing errors resulting in a permanent EMSGSIZE error during rule retrieval operations.
