An adjacent attacker can only indirectly nudge the local supplicant into scan/reconnect cycles, so delivery is local.\nAC:L - The attacker drives both sides of the race \u2014 it starts the hardware scan and issues the connect that invokes cancel_hw_scan \u2014 and the window is wide because the cancel thread blocks on `rtwdev-\u003emutex` for the entire duration of the firmware-driven completion work. The sequence can be repeated indefinitely until the race is won.\nPR:L - Only the ability to request scans and connections is needed; on typical desktop and mobile deployments an ordinary logged-in user can drive both through NetworkManager/wpa_supplicant (polkit/Settings), and the underlying nl80211 gate is the namespaced `GENL_UNS_ADMIN_PERM` capability rather than real root.\nUI:N - No victim action is needed \u2014 the attacker issues the scan and connect requests itself, and the crash trace shows the trigger arriving from the automatic `cfg80211_conn_work` SME reconnect path.\nS:U - The corruption and the crash are confined to the kernel\u0027s own memory and the rtw89 driver state; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `rtwvif-\u003escan_req`/`scan_ies` dangle into the kfree\u0027d, heap-sprayable `local-\u003ehw_scan_req`, and the driver dereferences pointers read out of it (`req-\u003echannels[idx]`, `req-\u003eies`), giving an attacker-groomable read primitive that can disclose kernel memory.\nI:H - The use-after-free on `local-\u003ehw_scan_req` lets an attacker reclaim the freed allocation and control the fields the driver uses to build firmware H2C commands and channel lists, which is exploitable for memory corruption and control-flow influence.\nA:H - The documented outcome is a kernel oops (`null-ptr-deref` on `req-\u003eno_cck`) inside a workqueue while `rtwdev-\u003emutex` and the wiphy mutex are held, killing the worker with locks held and leaving the wireless device \u2014 and potentially the system \u2014 hung."

There is no network-facing path into `bch2_fs_file_ioctl()`.\nAC:L - The attacker deterministically triggers both defects with a single ioctl call \u2014 no race, no memory-layout dependence, no timing window; the dcache state that wedges `bch2_evict_subvolume_inodes()` is created by the attacker simply by walking into the subvolume beforehand. No conditions lie outside the attacker\u0027s control.\nPR:L - `BCH_IOCTL_SUBVOLUME_DESTROY` has no `capable()` check and, before this fix, no `inode_permission()` check, so an ordinary unprivileged local user needs only an fd on the bcachefs mount plus search (`MAY_EXEC`) permission along the path to the victim subvolume. No CAP_SYS_ADMIN, no user-namespace trick, and no ownership of or write access to the target is required.\nUI:N - The attacker issues the ioctl directly with no action by any other user; the mounted bcachefs filesystem is an ambient system configuration, not a victim-performed step at exploit time.\nS:U - The vulnerable code and the impacted resources (kernel filesystem state, on-disk subvolume data) are managed by the same security authority \u2014 the kernel. This is a standard in-kernel DAC-bypass/DoS with no VM, IOMMU, or sandbox boundary crossed.\nC:L - There is no direct arbitrary-read primitive, but the DAC bypass has bounded disclosure consequences: after destroying a root- or other-user-owned subvolume in a directory the attacker can write to, the attacker can recreate the path and have a privileged process deposit sensitive data into attacker-controlled storage, and the non-invalidated dcache subtree leaves stale dentries/inodes referencing a freed subvolume ID that can be reused by another user\u0027s newly created subvolume.\nI:H - An unprivileged user can permanently destroy any subvolume they can merely traverse to \u2014 including root-owned subvolumes and other users\u0027 mode-0700 subvolumes \u2014 bypassing all ownership, write-permission, sticky-bit and non-empty-directory protections, which is unauthorized destruction of arbitrary data on the filesystem. The stale, still-hashed dentry subtree over a deleted subvolume additionally permits writes through inodes whose subvolume ID may be reused.\nA:H - The `d_delete()` bug leaves `bch2_evict_subvolume_inodes()` stuck in `TASK_UNINTERRUPTIBLE`, producing an unkillable D-state kworker that holds `BCH_WRITE_REF_snapshot_delete_pagecache` forever \u2014 unmount and read-only transitions hang, all further subvolume deletions stall, and recovery requires a reboot. Independently, arbitrary destruction of subvolumes (e.g. one holding `/home` or a database) is total loss of the affected data."

Then socket_match() can correctly check whether\nthe socket was transparent.\n\nHowever, the IPv6 counterpart (nf_sk_lookup_slow_v6) lacks this\nconntrack lookup, making xt_socket fail to match on the socket when the\npacket was SNATed. Add the same logic to nf_sk_lookup_slow_v6.\n\nIPv6 SNAT is used in Kubernetes clusters for pod-to-world packets, as\npods\u0027 addresses are in the fd00::/8 ULA subnet and need to be replaced\nwith the node\u0027s external address. Cilium leverages Envoy to enforce L7\npolicies, and Envoy uses transparent sockets. Cilium inserts an iptables\nprerouting rule that matches on `-m socket --transparent` and redirects\nthe packets to localhost, but it fails to match SNATed IPv6 packets due\nto that missing conntrack lookup."

This crash is caused by a NULL pointer\ndereference of dev-\u003eraw pointer, even though it is checked for NULL in\nthe same function, which means there is a race condition. It occurs due\nto the incorrect order of actions in the streamzap_disconnect() function:\nrc_unregister_device() is called before usb_kill_urb(). The dev-\u003eraw\npointer is freed and set to NULL in rc_unregister_device(), and only\nafter that usb_kill_urb() waits for in-progress requests to finish.\n\nIf rc_unregister_device() is called while streamzap_callback() handler is\nnot finished, this can lead to accessing freed resources. Thus\nrc_unregister_device() should be called after usb_kill_urb().\n\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller."
