Title
wifi: cfg80211: clear wdev->cqm_config pointer on free
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: cfg80211: clear wdev->cqm_config pointer on free
When we free wdev->cqm_config when unregistering, we also
need to clear out the pointer since the same wdev/netdev
may get re-registered in another network namespace, then
destroyed later, running this code again, which results in
a double-free.

No remote or adjacent network input is needed to create or trigger the double free.\nAC:L - The sequence is deterministic straight-line netlink configuration \u2014 set CQM thresholds, move the wiphy to another netns, then unregister again \u2014 with no race to win. The attacker also chooses `n_thresholds`, controlling the kmalloc bucket of the freed object and making heap reclaim reliable.\nPR:L - Every required command uses `GENL_UNS_ADMIN_PERM`, i.e. CAP_NET_ADMIN in the socket\u0027s user namespace, which an unprivileged user obtains via `unshare -Urn`; `get_net_ns_by_fd()` performs no additional capability check and hwsim radios are created in the caller\u0027s own netns.\nUI:N - The attacker performs all steps itself through netlink sockets; no victim action, mount, or file open is required.\nS:U - The corruption is confined to the kernel\u0027s own slab allocator and results in kernel-level compromise within the same security authority, with no VM, IOMMU, or sandbox boundary crossed.\nC:H - The double free lets the attacker overlap the freed chunk with a live victim object of a size they control, and the stale pointer is additionally read by `cfg80211_cqm_rssi_notify_work()`/`cfg80211_cqm_rssi_update()`, yielding a use-after-free read that can be escalated to arbitrary kernel memory disclosure.\nI:H - `kfree_rcu()` on the dangling pointer clobbers the first 16 bytes of a reclaimed object with an rcu_head and frees it a second time, and `cfg80211_cqm_rssi_notify()` writes attacker-influenced RSSI values into freed memory \u2014 a classic double-free/UAF write primitive leading to arbitrary write and control-flow hijack.\nA:H - A double free corrupts the SLUB freelist, causing immediate slab corruption BUG/KASAN reports and kernel panics, and can be triggered repeatedly by an unprivileged local user."
