This might cause memory corruption should\nwmi_char_open() be unable to find its driver, something which can\nhappen when the associated WMI device is deleted in wmi_free_devices().\n\nFix the problem by using the miscdevice pointer to retrieve the WMI\ndevice data associated with a char device using container_of(). This\nalso avoids wmi_char_open() picking a wrong WMI device bound to a\ndriver with the same name as the original driver."

There is no network or adjacent-link path into this platform/x86 WMI code.\nAC:H - Memory corruption requires wmi_char_open() to fail its driver lookup while misc_open still succeeds, which the fix ties to wmi_free_devices() list_del before misc_deregister—i.e. concurrent ACPI/platform WMI removal (e.g. rmmod wmi). An unprivileged attacker can spam open/ioctl but cannot induce that privileged teardown, matching other module-unload races scored AC:H.\nPR:L - The char device is registered with mode 0444, so any local unprivileged user can open it and issue read/ioctl; no init-namespace root or capability is required on the attacker’s side of the race.\nUI:N - The attacker opens and operates on the WMI char device in their own process; no victim action is required. Concurrent administrative device removal is Attack Complexity, not User Interaction.\nS:U - Type confusion / use-after-free stays inside the host kernel’s WMI/misc authority and does not cross a VM, IOMMU, or sandbox boundary.\nC:H - Failed lookup leaves filp->private_data as a miscdevice* that read/ioctl treat as struct wmi_block, causing out-of-bounds reads of adjacent heap; if the wblock is freed while the fd is held this becomes a UAF disclosure primitive, scored High per kernel guidance.\nI:H - The same type confusion/UAF makes wmi_ioctl() mutex_lock, dereference handler_data, and copy_from_user() through misinterpreted pointers—yielding heap corruption and an arbitrary-write primitive after reclaim, so Integrity is High.\nA:H - Misinterpreting a miscdevice as a wmi_block (or using a freed wblock) reliably leads to invalid memory access, oops/panic, or hang on corrupted locks; any such kernel crash/UAF is Availability High."
