CVE-2024-53088: i40e: fix race condition by adding filter's intermediate sync state

In the Linux kernel, the following vulnerability has been resolved: i40e: fix race condition by adding filter's intermediate sync state Fix a race condition in the i40e driver that leads to MAC/VLAN filters becoming corrupted and leaking. Address the issue that occurs under heavy load when multiple threads are concurrently modifying MAC/VLAN filters by setting mac and port VLAN. 1. Thread T0 allocates a filter in i40e_add_filter() within i40e_ndo_set_vf_port_vlan(). 2. Thread T1 concurrently frees the filter in __i40e_del_filter() within i40e_ndo_set_vf_mac(). 3. Subsequently, i40e_service_task() calls i40e_sync_vsi_filters(), which refers to the already freed filter memory, causing corruption. Reproduction steps: 1. Spawn multiple VFs. 2. Apply a concurrent heavy load by running parallel operations to change MAC addresses on the VFs and change port VLANs on the host. 3. Observe errors in dmesg: "Error I40E_AQ_RC_ENOSPC adding RX filters on VF XX, please set promiscuous on manually for VF XX". Exact code for stable reproduction Intel can't open-source now. The fix involves implementing a new intermediate filter state, I40E_FILTER_NEW_SYNC, for the time when a filter is on a tmp_add_list. These filters cannot be deleted from the hash list directly but must be removed using the full process.

Security readout for executives and security teams

Plain-English summary

CVE-2024-53088 is a Linux kernel i40e driver race condition. Under heavy concurrent changes to virtual function MAC and port VLAN settings, filter state can become corrupted and leaked, potentially disrupting network availability. It is not a remote internet-facing bug based on the supplied evidence.

Executive priority

Treat as a targeted availability risk for virtualized networking hosts, not a broad emergency. Prioritize patching systems where i40e virtual functions support production workloads or tenant-facing network isolation.

Technical view

The i40e driver could free a MAC/VLAN filter while another path still expects it during filter synchronization. The fix adds an intermediate I40E_FILTER_NEW_SYNC state for filters on the temporary add list, preventing direct deletion from the hash list during synchronization.

Likely exposure

Exposure is most likely on Linux hosts using the i40e driver with virtual functions and operational workflows that concurrently modify VF MAC addresses and port VLANs. Systems without that driver, without VFs, or without such local privileged configuration activity appear less exposed.

Exploitation context

The CVSS vector is local, high complexity, low privileges, no user interaction, and high availability impact. CISA KEV status is false in the supplied bundle, and no cited source states active exploitation. The provided reproduction detail is limited and not open-sourced.

Researcher notes

Evidence supports a race in i40e MAC/VLAN filter lifecycle handling. The source describes freed filter memory later referenced by i40e_sync_vsi_filters. Exact reproduction code is unavailable, so validation should focus on affected configuration, patch presence, and operational log symptoms.

Mitigation direction

  • Apply Linux kernel or distribution updates containing the referenced stable fixes.
  • Check vendor or distribution advisories for the correct fixed package version.
  • Reduce concurrent VF MAC and port VLAN changes until patched.
  • Monitor kernel logs for i40e RX filter ENOSPC errors.

Validation and detection

  • Inventory hosts using the Linux i40e driver and virtual functions.
  • Compare running kernel versions against vendor fixed packages or stable commits.
  • Review dmesg or centralized logs for i40e RX filter errors.
  • Run controlled regression tests for concurrent VF MAC and VLAN updates after patching.
