Subject: [PATCH 0/7] wifi: cfg80211: Annotate with __counted_by
Date: Thu, 17 Aug 2023 14:15:22 -0700 [thread overview]
Message-ID: <20230817211114.never.208-kees@kernel.org> (raw)
Hi,
This annotates several structures with the coming __counted_by attribute
for bounds checking of flexible arrays at run-time. As a note toward
applicability, had this mitigation been available already, the flaw
fixed in commit 6311071a0562 ("wifi: nl80211: fix integer overflow in
nl80211_parse_mbssid_elems()") would have already been unexploitable
(i.e. writes through an out-of-bounds index would have been blocked).
Thanks!
-Kees
