GHSA-V876-Q68F-39FV

Vulnerability from github – Published: 2024-05-17 15:31 – Updated: 2025-09-26 18:31

Details

In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: mvm: don't set the MFP flag for the GTK

The firmware doesn't need the MFP flag for the GTK, it can even make the firmware crash. in case the AP is configured with: group cipher TKIP and MFPC. We would send the GTK with cipher = TKIP and MFP which is of course not possible.

Severity

5.5 (Medium)

This requires the attacker to be within radio range on the same wireless segment, i.e. adjacent network.\nAC:L - An attacker operating an AP (including an evil twin on a network whose PSK is known or shared, such as caf\u00e9/office/guest Wi-Fi) fully controls the required configuration \u2014 group cipher TKIP with MFPC \u2014 and the crash follows deterministically on GTK installation, with no race or memory-layout dependency. The other precondition (PMF negotiated, so `sta-\u003emfp` is set) is the default on modern supplicants.\nPR:N - The attacker needs no account, capability, or any privilege on the victim system; they merely configure the AP the client associates with. No local access or kernel-side authorization is involved on the target.\nUI:N - wpa_supplicant/NetworkManager auto-reconnect to a known SSID after a deauth means the association and GTK installation happen with no user action. The vulnerable code runs as part of normal automated connection setup.\nS:U - The consequences are confined to the Wi-Fi device and the kernel driver managing it \u2014 the same security authority as the vulnerable component. No VM, IOMMU, or sandbox boundary is crossed.\nC:N - The defect is an incorrect flag bit in a firmware command; there is no out-of-bounds read, uninitialized data disclosure, or leak of kernel memory to the attacker.\nI:L - The group key is installed in firmware with the wrong protection semantics \u2014 flagged as en/decrypting management frames when a non-iGTK group key must not be \u2014 so management-frame protection state for the GTK is incorrect, which any group member could attempt to abuse for forged \"protected\" broadcast management frames. This is bounded, not arbitrary, modification.\nA:H - The malformed TKIP+MFP key command asserts the firmware, producing a SW-error dump and a full NIC restart with loss of wireless connectivity, and can be re-triggered on every reconnect attempt for a persistent denial of service. Firmware re-init after such asserts can also fail outright, leaving the adapter unusable until reboot."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
