  3. CVE-2025-21982
In the Linux kernel, the following vulnerability has been resolved: pinctrl: nuvoton: npcm8xx: Add NULL check in npcm8xx_gpio_fw devm_kasprintf() calls can return null pointers on failure. But the return values were not checked in npcm8xx_gpio_fw(). Add NULL check in npcm8xx_gpio_fw(), to handle kernel NULL pointer dereference error.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: pinctrl: nuvoton: npcm8xx: Se ha añadido una comprobación de valores nulos en las llamadas a npcm8xx_gpio_fw devm_kasprintf(), que pueden devolver punteros nulos en caso de error. Sin embargo, los valores de retorno no se comprobaron en npcm8xx_gpio_fw(). Se ha añadido una comprobación de valores nulos en npcm8xx_gpio_fw() para gestionar el error de desreferencia de punteros nulos del kernel.
