CVE-2024-35838: wifi: mac80211: fix potential sta-link leak

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix potential sta-link leak When a station is allocated, links are added but not set to valid yet (e.g. during connection to an AP MLD), we might remove the station without ever marking links valid, and leak them. Fix that.

Security readout for executives and security teams

Plain-English summary

CVE-2024-35838 is a Linux kernel Wi-Fi bug in mac80211. Under certain station setup/removal conditions, link objects may be leaked. The public record does not provide CVSS, confirmed impact, or exploitation evidence. Business urgency is mainly for Linux endpoints and devices that actively use Wi-Fi.

Executive priority

Treat as routine-to-moderate patch management for Wi-Fi-enabled Linux fleets. Prioritize mobile, workstation, and embedded wireless devices. Do not escalate as an emergency based on current sources because severity and exploitation are not established.

Technical view

The issue is described as a potential sta-link leak in Linux mac80211. When a station is allocated and links are added but not yet marked valid, such as during connection to an AP MLD, removing the station can leak those links. Stable kernel commits are referenced as fixes.

Likely exposure

Likely exposed systems are Linux kernels in affected ranges using mac80211 Wi-Fi functionality, especially clients interacting with AP MLD scenarios. Servers or appliances without Wi-Fi are less likely to be exposed. Distribution package applicability must be verified against vendor advisories.

Exploitation context

No active exploitation is indicated by KEV, and the provided sources do not describe public exploitation. The record describes a memory/resource leak condition, but does not quantify denial-of-service impact, trigger reliability, or attacker prerequisites.

Researcher notes

Evidence is limited to the CVE record and Linux stable commits. No CWE, CVSS, exploit status, or detailed threat model is provided. Review the linked commits and downstream distro advisories to determine exact branch exposure and fixed package versions.

Mitigation direction

  • Apply vendor or distribution kernel updates that include the referenced stable fixes.
  • If packages are unavailable, consult vendor guidance before backporting kernel commits.
  • Prioritize Linux laptops, workstations, and embedded devices that actively use Wi-Fi.

Validation and detection

  • Inventory Linux kernel versions across Wi-Fi-capable assets.
  • Check distribution advisories for CVE-2024-35838 package mapping.
  • Confirm the running kernel includes one referenced stable fix commit.
  • Verify whether affected systems use mac80211-based wireless networking.
