CVE-2025-38297

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2025-38297
In the Linux kernel, the following vulnerability has been resolved: PM: EM: Fix potential division-by-zero error in em_compute_costs() When the device is of a non-CPU type, table[i].performance won't be initialized in the previous em_init_performance(), resulting in division by zero when calculating costs in em_compute_costs(). Since the 'cost' algorithm is only used for EAS energy efficiency calculations and is currently not utilized by other device drivers, we should add the _is_cpu_device(dev) check to prevent this division-by-zero issue.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: PM: EM: Se corrige un posible error de división por cero en em_compute_costs(). Cuando el dispositivo no es de tipo CPU, table[i].performance no se inicializa en la función em_init_performance() anterior, lo que resulta en una división por cero al calcular los costos en em_compute_costs(). Dado que el algoritmo "cost" solo se utiliza para cálculos de eficiencia energética de EAS y actualmente no lo utilizan otros controladores de dispositivos, se debe agregar la comprobación _is_cpu_device(dev) para evitar este problema de división por cero.
