CVE-2024-35912: wifi: iwlwifi: mvm: rfi: fix potential response leaks

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: rfi: fix potential response leaks If the rx payload length check fails, or if kmemdup() fails, we still need to free the command response. Fix that.

Security readout for executives and security teams

Plain-English summary

This is a Linux kernel driver bug in Intel iwlwifi wireless code. Under certain error paths, the driver could fail to free a command response, causing a resource leak. The public sources do not provide CVSS, impact rating, or evidence of real-world exploitation.

Executive priority

Treat as a kernel hygiene item with uncertain severity. It should be handled through normal endpoint patch cycles, with added attention to Linux laptops or workstations using Intel Wi-Fi.

Technical view

The fix frees an iwlwifi command response when receive payload length validation fails or kmemdup() allocation fails in the mvm RFI path. The described weakness is a cleanup error on failure paths, not a documented privilege escalation or remote code execution issue in the provided sources.

Likely exposure

Exposure is most likely on Linux systems using affected kernels with Intel Wi-Fi hardware driven by iwlwifi. Exact distro exposure depends on vendor backports and kernel package status; verify against the running kernel and vendor advisories.

Exploitation context

CISA KEV status is false in the supplied data, and no cited source states active exploitation. The source bundle does not describe exploit prerequisites, attacker position, or practical triggerability.

Researcher notes

The available record only documents a response leak fixed in iwlwifi mvm RFI error handling. There is insufficient public evidence here to rate exploitability, affected configurations beyond Linux iwlwifi, or security impact beyond potential resource leakage.

Mitigation direction

  • Apply vendor Linux kernel updates that include the referenced stable fixes.
  • Prioritize laptops and endpoints using Intel Wi-Fi with iwlwifi loaded.
  • Reboot systems into the updated kernel after patch installation.
  • Check distribution advisories before assuming upstream version numbers map directly.
  • Monitor vendor guidance because no standalone mitigation is named.

Validation and detection

  • Inventory running kernel versions across Linux endpoints and servers.
  • Identify systems with Intel Wi-Fi hardware and the iwlwifi module loaded.
  • Confirm installed kernel packages include the relevant upstream stable commits.
  • Review distro security advisories for CVE-2024-35912 package status.
  • Verify post-reboot that systems are running the fixed kernel.
