CVE-2026-46166

Description

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.
