What does CVE-2026-68472 affect?
CVE-2026-68472 affects Linux kernel (cfg80211 EHT MLE), Linux-based laptops/desktops, Embedded devices/routers using affected kernels. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-68472?
Install vendor/kernel and firmware updates; avoid untrusted APs and update Wi‑Fi drivers
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Remote attacker in Wi‑Fi range can send crafted MBSSID/EHT MLE beacons to cause kernel out‑of‑bounds read, leading to crash (DoS) and possible memory disclosure.

As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
