Description OSIDB Bzimport 2026-08-10 12:25:34 UTC 
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.
