leftover rfkill objects are later driven via /dev/rfkill (rfkill_fop_write), not by a network or radio protocol message.\nAC:H - The dangling asus_rfkill exists only when asus_screenpad_init() returns an error other than -ENODEV after asus_wmi_rfkill_init() has registered devices, which requires an ACPI WMI failure from asus_wmi_get_devstate()/asus_wmi_evaluate_method() or backlight_device_register() failure that the attacker cannot induce.\nPR:L - After fail_screenpad skips asus_wmi_rfkill_exit(), the leaked rfkill stays on rfkill_list; rfkill_fop_write() has no capable() check, so a local session user who can open /dev/rfkill (typical laptop rfkill group/uaccess) can send RFKILL_OP_CHANGE and reach asus_rfkill_set() without CAP_SYS_ADMIN.\nUI:N - The attacker themselves writes RFKILL_OP_CHANGE/CHANGE_ALL to /dev/rfkill targeting the leaked asus-wlan/asus-bluetooth rfkill idx; no other user must mount media, plug a device, or confirm a prompt.\nS:U - kfree(asus) on the asus_wmi_add() fail_screenpad path and the later asus_rfkill_query()/asus_rfkill_set() dereference of priv->asus occur in the host kernel; this is not a KVM/Xen guest escape or IOMMU/DMA bypass.\nC:H - fail_screenpad jumps past asus_wmi_rfkill_exit() and then kfree(asus) while rfkill->data still points at the embedded struct asus_rfkill; rfkill_set_block() calls asus_rfkill_query(), which reads priv->asus and priv->dev_id from that freed object, a kernel UAF read.\nI:H - The same dangling rfkill->data is passed to asus_rfkill_set()/asus_rfkill_wlan_set(), which use priv->asus->driver and mutex_lock(&asus->wmi_lock); the leaked backlight_device also keeps bl_get_data()==asus for update_bl_status(), so reclaiming the freed asus_wmi object is a write/control-flow primitive.\nA:H - asus_rfkill_query() and asus_rfkill_set() dereference the kfree'd struct asus_wmi, and asus_rfkill_wlan_set() takes asus->wmi_lock in freed memory, which oopses; fail_custom_fan_curve also skips asus_wmi_input_exit(), leaving a registered input_dev until reboot."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/platform/x86/asus-wmi.c"], "versions": [{"version": "0f0ac158d28ff78e75c334e869b1cb8e69372a1f", "lessThan": "72d792c8053f238ae541fdaa90e609548509b65f", "status": "affected", "versionType": "git"}, {"version": "0f0ac158d28ff78e75c334e869b1cb8e69372a1f", "lessThan": "959ed35f8c8f07b8dd43c3f917a43ae2f77e4471", "status": "affected", "versionType": "git"}, {"version": "0f0ac158d28ff78e75c334e869b1cb8e69372a1f", "lessThan": "8d5999608da60db45949e5459f74f581cdaacd04", "status": "affected", "versionType": "git"}, {"version": "0f0ac158d28ff78e75c334e869b1cb8e69372a1f", "lessThan": "8410cd2690d463b60527d00ac8cffea2d5a041f6", "status": "affected", "versionType": "git"}, {"version": "0f0ac158d28ff78e75c334e869b1cb8e69372a1f", "lessThan": "3308b8c5f5a28403611a2f5a46f06aabe4f0c661", "status": "affected", "versionType": "git"}, {"version": "0f0ac158d28ff78e75c334e869b1cb8e69372a1f", "lessThan": "ef3daa2b84a2b8499ce9e2ce1c865dca36d39f95", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/platform/x86/asus-wmi.c"], "versions": [{"version": "5.17", "status": "affected"}, {"version": "0", "lessThan": "5.17", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.191", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.160", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.114", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.57", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.2.6", "lessThanOrEqual": "7.2.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.3", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "6.1.191"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "6.6.160"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "6.12.114"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "6.18.57"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "7.2.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.17", "versionEndExcluding": "7.3"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/72d792c8053f238ae541fdaa90e609548509b65f"}, {"url": "https://git.kernel.org/stable/c/959ed35f8c8f07b8dd43c3f917a43ae2f77e4471"}, {"url": "https://git.kernel.org/stable/c/8d5999608da60db45949e5459f74f581cdaacd04"}, {"url": "https://git.kernel.org/stable/c/8410cd2690d463b60527d00ac8cffea2d5a041f6"}, {"url": "https://git.kernel.org/stable/c/3308b8c5f5a28403611a2f5a46f06aabe4f0c661"}, {"url": "https://git.kernel.org/stable/c/ef3daa2b84a2b8499ce9e2ce1c865dca36d39f95"}], "title": "platform/x86: asus-wmi: fix resource leaks on probe failure", "x_generator": {"engine": "bippy-1.2.0"}}}}
