That path is reached from local_pci_probe() as the .probe of rtl8192ce/rtl8188ee/rtl8192ee/rtl8723be and related pci_driver tables (e.g. Realtek 0x8191/0x8178). 802.11 frames never enter rtl_pci_probe.\nAC:H - The only trigger is pci_enable_msi() or request_irq(pdev->irq, _rtl_pci_interrupt, IRQF_SHARED) failing after ieee80211_register_hw() has already succeeded. pdev->irq is assigned by the host PCI/ACPI code, and the subsequent irqaction kzalloc is tiny compared with earlier ring and wiphy allocations, so an attacker cannot reliably force that failure.\nPR:L - Once fail3 has run ieee80211_free_hw() on the still-registered hw, the leftover default wlan vif from ieee80211_if_add(), cfg80211 wiphy, inetaddr notifiers, and rfkill poll are reachable via nl80211 or any netns address change without init-namespace root or PCI sysfs bind.\nUI:N - No victim must mount media or associate to a network; after the failed probe unwind, the attacker\u2019s own nl80211 use of the leftover wlan vif, an inetaddr change, or cfg80211_rfkill_poll touches the still-registered ieee80211_local.\nS:U - ieee80211_free_hw() frees the still-registered ieee80211_local/wiphy while mac80211 still holds it; impact is host-kernel heap corruption, not a VM, IOMMU, or sandbox escape.\nC:H - fail3 calls ieee80211_free_hw() without ieee80211_unregister_hw(), so cfg80211_rfkill_poll \u2192 ieee80211_rfkill_poll and nl80211 still dereference the kfree'd ieee80211_local, wiphy bands, and default STA vif, a UAF read primitive.\nI:H - The leftover objects are written by ieee80211_ifa_changed (inetaddr notifier), mac80211 workqueues never torn down by ieee80211_unregister_hw(), and rtl_op_rfkill_poll via wiphy_rfkill_start_polling, enabling UAF writes and control-flow hijack.\nA:H - ieee80211_free_hw() without ieee80211_unregister_hw() leaves mac80211 workqueues, inetaddr notifiers, the default wlan vif, and rfkill polling running against freed ieee80211_local, which oopses or panics on the next access."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo":
