CVSS: 4.4EPSS: 0%CPEs: 8EXPL: 0CVE-2023-52864 – platform/x86: wmi: Fix opening of char device
https://notcve.org/view.php?id=CVE-2023-52864
In the Linux kernel, the following vulnerability has been resolved: platform/x86: wmi: Fix opening of char device Since commit fa1f68db6ca7 ("drivers: misc: pass miscdevice pointer via file private data"), the miscdevice stores a pointer to itself inside filp->private_data, which means that private_data will not be NULL when wmi_char_open() is called. This might cause memory corruption should wmi_char_open() be unable to find its driver, something which can happen when the associated WMI device is deleted in wmi_free_devices(). Fix the problem by using the miscdevice pointer to retrieve the WMI device data associated with a char device using container_of(). This also avoids wmi_char_open() picking a wrong WMI device bound to a driver with the same name as the original driver. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: plataforma/x86: wmi: corrige la apertura del dispositivo char. Desde la confirmación fa1f68db6ca7 ("drivers: misc: pasar el puntero del dispositivo misc a través de datos privados del archivo"), el dispositivo misc almacena un puntero a sí mismo en su interior. filp->private_data, lo que significa que private_data no será NULL cuando se llame a wmi_char_open(). • https://git.kernel.org/stable/c/44b6b7661132b1b0e5fd3147ded66f1e4a817ca9 https://git.kernel.org/stable/c/cf098e937dd125c0317a0d6f261ac2a950a233d6 https://git.kernel.org/stable/c/9fb0eed09e1470cd4021ff52b2b9dfcbcee4c203 https://git.kernel.org/stable/c/d426a2955e45a95b2282764105fcfb110a540453 https://git.kernel.org/stable/c/e0bf076b734a2fab92d8fddc2b8b03462eee7097 https://git.kernel.org/stable/c/44a96796d25809502c75771d40ee693c2e44724e https://git.kernel.org/stable/c/36d85fa7ae0d6be651c1a745191fa7ef055db43e https://git.kernel.org/stable/c/fb7b06b59c6887659c6ed0ecd3110835e • CWE-402: Transmission of Private Resources into a New Sphere ('Resource Leak') •

Se podría llamar a axi_fan_control_irq_handler(), dependiente de la estructura privada axi_fan_control_data, antes de que se registre el dispositivo hwmon.
