Answer in brief
CVE-2026-68407 records a Unknown severity vulnerability in wifi: nl80211: free RNR data on MBSSID mismatch. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: free RNR data on MBSSID mismatch nl80211_parse_beacon() rejects EMA RNR data when there are fewer RNR entries than MBSSID entries. The rejected RNR allocation has not been attached to the beacon data yet, so free it before returning the error.
