CVE-2026-98028

Description

A flaw was found in the Linux kernel's Netronome Flow Processor (NFP) network driver. When replacing an existing flow steering rule fails during hardware reprogramming, the driver fails to remove the old rule from its internal list, creating an inconsistency with the active rule counter. A local user with network administration privileges could trigger this condition, causing subsequent flow rule queries to fail permanently or potentially resulting in memory corruption. This issue primarily leads to a Denial of Service (DoS) for network management operations.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
