Title
wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: check/clear fast rx for non-4addr sta VLAN changes When moving a station out of a VLAN and deleting the VLAN afterwards, the fast_rx entry still holds a pointer to the VLAN's netdev, which can cause use-after-free bugs. Fix this by immediately calling ieee80211_check_fast_rx after the VLAN change.

This is link-local 802.11 reachability, not routable network reach, hence Adjacent.\nAC:L - Once the station has been moved out of a VLAN that is subsequently deleted, every subsequent data frame the attacker transmits deterministically dereferences the freed netdev \u2014 there is no race to win and no memory layout the attacker cannot influence. In a hostapd dynamic-VLAN deployment the attacker induces the move itself by reauthenticating into a different RADIUS-assigned VLAN, and can repeat the sequence at will.\nPR:L - `ieee80211_check_fast_rx` only installs a `fast_rx` entry for a station with `WLAN_STA_AUTHORIZED` and a CCMP/GCMP PTK, so the attacker must be an authenticated, authorized client of the WLAN. That is an ordinary low-privileged network user, not an administrator.\nUI:N - No victim action is needed \u2014 the VLAN reassignment and teardown are performed automatically by hostapd in response to the attacker\u0027s own (re)authentication, and the attacker\u0027s own transmitted frames trigger the dereference.\nS:U - The use-after-free corrupts kernel memory and is exploited within the kernel\u0027s own security authority on the AP; there is no hypervisor, IOMMU, or sandbox boundary crossed.\nC:H - The freed `struct net_device` is read for `-\u003etstats`, `-\u003edev_addr` and `-\u003end_net`, and the skb is delivered into the stack using that stale pointer, so a groomed reclaim yields controlled kernel reads and misdirected traffic delivery; if the slot is reused by a live netdev, the station\u0027s frames leak into a different VLAN, defeating the segmentation the VLAN exists to enforce.\nI:H - `dev_sw_netstats_rx_add(fast_rx-\u003edev, skb-\u003elen)` reads a per-CPU pointer out of the freed object and writes `rx_bytes += skb-\u003elen` (attacker-chosen length) plus `rx_packets++` through it, giving a repeatable, attacker-influenced arbitrary-increment write primitive; combined with the UAF read this is exploitable for control-flow hijacking, and the stale `dev` also permits frame injection into the wrong VLAN.\nA:H - Dereferencing a freed `net_device` from RX softirq context \u2014 including an indirect write through a dangling `-\u003etstats` and passing the freed device to `eth_type_trans`/`netif_receive_skb` \u2014 reliably oopses or panics the access point kernel on the first frame after VLAN teardown."

This is link-local 802.11 reachability, not routable network reach, hence Adjacent.\\nAC:L - Once the station has been moved out of a VLAN that is subsequently deleted, every subsequent data frame the attacker transmits deterministically dereferences the freed netdev \\u2014 there is no race to win and no memory layout the attacker cannot influence. In a hostapd dynamic-VLAN deployment the attacker induces the move itself by reauthenticating into a different RADIUS-assigned VLAN, and can repeat the sequence at will.\\nPR:L - `ieee80211_check_fast_rx` only installs a `fast_rx` entry for a station with `WLAN_STA_AUTHORIZED` and a CCMP/GCMP PTK, so the attacker must be an authenticated, authorized client of the WLAN. That is an ordinary low-privileged network user, not an administrator.\\nUI:N - No victim action is needed \\u2014 the VLAN reassignment and teardown are performed automatically by hostapd in response to the attacker\u0027s own (re)authentication, and the attacker\u0027s own transmitted frames trigger the dereference.\\nS:U - The use-after-free corrupts kernel memory and is exploited within the kernel\u0027s own security authority on the AP; there is no hypervisor, IOMMU, or sandbox boundary crossed.\\nC:H - The freed `struct net_device` is read for `-\u003etstats`, `-\u003edev_addr` and `-\u003end_net`, and the skb is delivered into the stack using that stale pointer, so a groomed reclaim yields controlled kernel reads and misdirected traffic delivery; if the slot is reused by a live netdev, the station\u0027s frames leak into a different VLAN, defeating the segmentation the VLAN exists to enforce.\\nI:H - `dev_sw_netstats_rx_add(fast_rx-\u003edev, skb-\u003elen)` reads a per-CPU pointer out of the freed object and writes `rx_bytes += skb-\u003elen` (attacker-chosen length) plus `rx_packets++` through it, giving a repeatable, attacker-influenced arbitrary-increment write primitive; combined with the UAF read this is exploitable for control-flow hijacking, and the stale `dev` also permits frame injection into the wrong VLAN.\\nA:H - Dereferencing a freed `net_device` from RX softirq context \\u2014 including an indirect write through a dangling `-\u003etstats` and passing the freed device to `eth_type_trans`/`netif_receive_skb` \\u2014 reliably oopses or panics the access point kernel on the first frame after VLAN teardown.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\",
