In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: use safe list iteration in radar detect work
The call to ieee80211_dfs_cac_cancel can cause the iterated chanctx to
be freed and removed from the list. Guard against this to avoid a
slab-use-after-free error.
A flaw was found in the Linux kernel's mac80211 wireless subsystem. This vulnerability arises from unsafe list iteration during radar detection work, where a channel context can be freed while still being processed. This can lead to a use-after-free memory error. A successful exploit could result in system instability or a denial of service.
