This vulnerability occurs when the driver attempts to send a Wi-Fi 6E (6th Generation Extended) related command, specifically `MCC_ALLOWED_AP_TYPE_CMD`, to a device that does not support Wi-Fi 6E. Due to the device's firmware mistakenly advertising support for this command, sending it can lead to a firmware crash. This could result in a Denial of Service (DoS) for the affected Wi-Fi functionality.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 9 · no fix planned: Red Hat Enterprise Linux 9, Red Hat Enterprise Linux 10 · updated 2026-10-23 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-43325.json)\n\n**kernel: wifi: iwlwifi: mvm: don't send a 6E related command when not supported** — rated Moderate by Red Hat.
