Subject: [PATCH wireless] wifi: mac80211_hwsim: fully initialise PMSR capabilities
Date: Tue, 3 Mar 2026 12:37:39 +0100 [thread overview]
Message-ID: <20260303113739.176403-2-johannes@sipsolutions.net> (raw)
From: Johannes Berg <johannes.berg@intel.com>
Since the recent additions to PMSR capabilities, it's no longer
sufficient to call parse_pmsr_capa() here since the capabilities
that were added aren't represented/filled by it. Always init the
data to zero to avoid using uninitialized memory.
Fixes: 86c6b6e4d187 ("wifi: nl80211/cfg80211: add new FTM capabilities")
Reported-by: syzbot+c686c6b197d10ff3a749@syzkaller.appspotmail.com
Closes: https://lore.kernel.org/69a67aa3.a70a0220.b118c.000a.GAE@google.com/
