No remote or adjacent peer can drive `.get_txpower`.\nAC:L - There is no race, no memory-grooming requirement, and no attacker-uncontrollable condition; the attacker simply issues the request and can poll indefinitely until a wireless vif is in the not-in-driver state, which is the persistent default on rfkill'd/Wi-Fi-off systems, on created-but-unstarted vifs, and on every vif after a hw-restart reconfig failure.\nPR:L - A plain unprivileged local account suffices — `NL80211_CMD_GET_INTERFACE` is explicitly marked in the nl80211 ops table as retrievable by unprivileged users (no `GENL_ADMIN_PERM`), and `wext_permission_check()` requires `CAP_NET_ADMIN` only for SET ioctls, leaving `SIOCGIWTXPOW` open to anyone.\nUI:N - The attacker triggers the bug entirely on their own by running `iw dev` or `iwconfig`; no action by any other user or administrator is needed at the time of exploitation.\nS:U - The uninitialized/stale dereference happens in kernel driver code and its consequences stay within the kernel's own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - On all pre-6.11 affected branches `vif->drv_priv` is never cleared after `remove_interface()`, so the driver dereferences pointers to freed objects — a use-after-free read whose result is additionally returned to userspace as the tx-power value via `NL80211_ATTR_WIPHY_TX_POWER_LEVEL`/`iwconfig`, leaking kernel memory contents.\nI:H - Driver `.get_txpower` handlers operate on the stale private area (dereferencing freed pointers, taking locks and walking driver structures through them), and a use-after-free on attacker-reclaimable heap memory is leverageable for controlled writes and control-flow influence, so integrity impact is scored High.\nA:H - Dereferencing uninitialized or freed driver private data reliably oopses the kernel — the fix's own rationale is \"avoid potentially crashing in the driver because of uninitialized private data\" — and any unprivileged user can retrigger it at will." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
