Publication date: 2026-08-15

Last updated on: 2026-08-17

Assigner: kernel.org

Description

In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: Validate NIX maximum LFs correctly NIX maximum number of LFs can be set via devlink command but that can be done before assigning any LFs to a PF/VF. The condition used to check whether any LFs are assigned is incorrect. This patch fixes that condition.

Executive Summary

This vulnerability in the Linux kernel involves incorrect validation of the NIX maximum LFs (Logical Functions) in the octeontx2-af driver. The issue occurs when setting the maximum number of LFs via a devlink command before assigning any LFs to a PF/VF. The condition used to check if LFs are assigned is flawed, allowing incorrect configurations.

Detection Guidance

This vulnerability is specific to the Linux kernel's octeontx2-af driver and involves incorrect validation of NIX maximum LFs. Detection requires checking kernel logs for related errors or examining the driver's behavior during LF assignment. Commands like dmesg or journalctl may show relevant errors, but no direct detection commands are provided in the context.

Impact Analysis

This vulnerability could lead to improper resource allocation in the Linux kernel's octeontx2-af driver, potentially causing system instability or unexpected behavior. If exploited, it might allow unauthorized access to logical functions or disrupt network operations.

Compliance Impact

This vulnerability does not directly affect compliance with GDPR, HIPAA, or similar standards as it pertains to a specific kernel-level issue in the octeontx2-af driver. No evidence suggests it impacts data protection, privacy, or security controls required by these regulations.

Mitigation Strategies

Update the Linux kernel to the patched version to resolve the octeontx2-af NIX LF validation issue. Monitor vendor advisories for specific kernel updates addressing this CVE.
