Title
HID: intel-ish-hid: Fix use-after-free issue in ishtp_hid_remove()
Summary
In the Linux kernel, the following vulnerability has been resolved: HID: intel-ish-hid: Fix use-after-free issue in ishtp_hid_remove() The system can experience a random crash a few minutes after the driver is removed. This issue occurs due to improper handling of memory freeing in the ishtp_hid_remove() function. The function currently frees the `driver_data` directly within the loop that destroys the HID devices, which can lead to accessing freed memory. Specifically, `hid_destroy_device()` uses `driver_data` when it calls `hid_ishtp_set_feature()` to power off the sensor, so freeing `driver_data` beforehand can result in accessing invalid memory. This patch resolves the issue by storing the `driver_data` in a temporary variable before calling `hid_destroy_device()`, and then freeing the `driver_data` after the device is destroyed.

This issue occurs due to improper handling of memory freeing in\\nthe ishtp_hid_remove() function.\\n\\nThe function currently frees the `driver_data` directly within the loop\\nthat destroys the HID devices, which can lead to accessing freed memory.\\nSpecifically, `hid_destroy_device()` uses `driver_data` when it calls\\n`hid_ishtp_set_feature()` to power off the sensor, so freeing\\n`driver_data` beforehand can result in accessing invalid memory.\\n\\nThis patch resolves the issue by storing the `driver_data` in a temporary\\nvariable before calling `hid_destroy_device()`, and then freeing the\\n`driver_data` after the device is destroyed.\"},{\"lang\":\"es\",\"value\":\"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: HID: intel-ish-hid: soluciona el problema de use-after-free en ishtp_hid_remove() El sistema puede experimentar un bloqueo aleatorio unos minutos despu\u00e9s de eliminar el controlador. Este problema se produce debido a la gesti\u00f3n incorrecta de la liberaci\u00f3n de memoria en la funci\u00f3n ishtp_hid_remove(). La funci\u00f3n actualmente libera `driver_data` directamente dentro del bucle que destruye los dispositivos HID, lo que puede llevar al acceso a la memoria liberada. Espec\u00edficamente, `hid_destroy_device()` usa `driver_data` cuando llama a `hid_ishtp_set_feature()` para apagar el sensor, por lo que liberar `driver_data` de antemano puede resultar en el acceso a memoria no v\u00e1lida.
