CVE-2024-35975: octeontx2-pf: Fix transmit scheduler resource leak

In the Linux kernel, the following vulnerability has been resolved: octeontx2-pf: Fix transmit scheduler resource leak Inorder to support shaping and scheduling, Upon class creation Netdev driver allocates trasmit schedulers. The previous patch which added support for Round robin scheduling has a bug due to which driver is not freeing transmit schedulers post class deletion. This patch fixes the same.

Security readout for executives and security teams

Plain-English summary

This Linux kernel issue is a resource leak in the octeontx2-pf network driver. When traffic-control classes are deleted, transmit scheduler resources may not be freed. Business impact is most relevant for systems using this specific driver and kernel path, where repeated configuration changes could degrade availability over time.

Executive priority

Moderate operational follow-up is appropriate for affected Linux networking systems. There is no cited active exploitation or severity score, but kernel resource leaks can become availability issues on infrastructure that uses the affected driver path.

Technical view

The vulnerable code is in the Linux kernel octeontx2-pf driver. Scheduler resources allocated during class creation for shaping and scheduling were not released after class deletion. The referenced stable commits fix the cleanup behavior. The sources do not provide CVSS, CWE, exploitability detail, or broader impact analysis.

Likely exposure

Exposure appears limited to Linux systems running affected kernel versions or backports that include the vulnerable octeontx2-pf driver behavior, especially where the relevant networking class creation and deletion functionality is used.

Exploitation context

The source bundle does not show CISA KEV listing, active exploitation, public exploit activity, or an external attacker path. Treat this as an availability and resource-management risk until vendor advisories clarify practical impact.

Researcher notes

Key unknowns are practical triggerability, required privileges, and measurable resource exhaustion impact. The official description ties the bug to class creation and deletion in the octeontx2-pf transmit scheduler path; avoid assuming remote exploitability without additional evidence.

Mitigation direction

  • Apply Linux kernel or distribution updates containing the referenced stable fixes.
  • Check your Linux vendor advisory for affected package versions and backport status.
  • Prioritize systems using the octeontx2-pf network driver.
  • Track kernel maintenance windows for network appliances and specialized ARM platforms.

Validation and detection

  • Inventory hosts running Linux kernels listed as affected in the source bundle.
  • Confirm whether the octeontx2-pf driver is present and in use.
  • Verify the running kernel includes one of the referenced stable fixes or a vendor backport.
  • Review vendor security notes for package-specific fixed versions.
