CVE-2025-23136

Estado: ModificadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

thermal: int340x: Add NULL check for adev

Not all devices have an ACPI companion fwnode, so adev might be NULL. This is similar to the commit cd2fd6eab480 ("platform/x86: int3472: Check for adev == NULL").

Add a check for adev not being set and return -ENODEV in that case to avoid a possible NULL pointer deref in int3402_thermal_probe().

Note, under the same directory, int3400_thermal_probe() has such a check.

No todos los dispositivos tienen un nodo auxiliar ACPI, por lo que adev podría ser nulo. Esto es similar a el commit cd2fd6eab480 (\"plataforma/x86: int3472: Comprobar si adev == NULL\"). Añadir una comprobación para comprobar si adev no está configurado y devolver -ENODEV en ese caso para evitar una posible desreferencia de puntero nulo en int3402_thermal_probe(). Cabe destacar que, en el mismo directorio, int3400_thermal_probe() cuenta con dicha comprobación. [rjw: Edición del tema, correcciones añadidas]"
