Summary
In the Linux kernel, the following vulnerability has been resolved: acpi: nfit: fix narrowing conversion in acpi_nfit_ctl Syzkaller has reported a warning in to_nfit_bus_uuid(): "only secondary bus families can be translated". This warning is emited if the argument is equal to NVDIMM_BUS_FAMILY_NFIT == 0. Function acpi_nfit_ctl() first verifies that a user-provided value call_pkg->nd_family of type u64 is not equal to 0. Then the value is converted to int, and only after that is compared to NVDIMM_BUS_FAMILY_MAX. This can lead to passing an invalid argument to acpi_nfit_ctl(), if call_pkg->nd_family is non-zero, while the lower 32 bits are zero. Furthermore, it is best to return EINVAL immediately upon seeing the invalid user input. The WARNING is insufficient to prevent further undefined behavior based on other invalid user input. All checks of the input value should be applied to the original variable call_pkg->nd_family. [iweiny: update commit message]

Syzkaller ha informado de una advertencia en to_nfit_bus_uuid(): \\\"Solo se pueden traducir familias de bus secundarias\\\". Esta advertencia se emite si el argumento es igual a NVDIMM_BUS_FAMILY_NFIT == 0. La funci\u00f3n acpi_nfit_ctl() verifica primero que el valor proporcionado por el usuario, call_pkg-\u0026gt;nd_family, de tipo u64, no sea igual a 0. A continuaci\u00f3n, el valor se convierte a int y solo despu\u00e9s se compara con NVDIMM_BUS_FAMILY_MAX. Esto puede provocar que se pase un argumento no v\u00e1lido a acpi_nfit_ctl() si call_pkg-\u0026gt;nd_family es distinto de cero, mientras que los 32 bits inferiores son cero. Adem\u00e1s, se recomienda devolver EINVAL inmediatamente despu\u00e9s de detectar la entrada de usuario no v\u00e1lida. La advertencia no es suficiente para evitar un comportamiento indefinido posterior basado en otra entrada de usuario no v\u00e1lida. Todas las comprobaciones del valor de entrada deben aplicarse a la variable original call_pkg-\u0026gt;nd_family.
