  3. CVE-2025-22099
In the Linux kernel, the following vulnerability has been resolved: drm: xlnx: zynqmp_dpsub: Add NULL check in zynqmp_audio_init devm_kasprintf() calls can return null pointers on failure. But some return values were not checked in zynqmp_audio_init(). Add NULL check in zynqmp_audio_init(), avoid referencing null pointers in the subsequent code.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm: xlnx: zynqmp_dpsub: Se ha añadido una comprobación de valores nulos en las llamadas a zynqmp_audio_init devm_kasprintf(), que pueden devolver punteros nulos en caso de error. Sin embargo, algunos valores de retorno no se comprobaron en zynqmp_audio_init(). Se ha añadido una comprobación de valores nulos en zynqmp_audio_init() para evitar referencias a punteros nulos en el código posterior.
