CVE-2025-23136

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-23136
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. [ rjw: Subject edit, added Fixes: ]

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: térmica: int340x: Añadir comprobación de valores nulos para adev. 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]
