  3. CVE-2025-37974
In the Linux kernel, the following vulnerability has been resolved: s390/pci: Fix missing check for zpci_create_device() error return The zpci_create_device() function returns an error pointer that needs to be checked before dereferencing it as a struct zpci_dev pointer. Add the missing check in __clp_add() where it was missed when adding the scan_list in the fixed commit. Simply not adding the device to the scan list results in the previous behavior.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: s390/pci: Se corrige la falta de comprobación para el retorno del error zpci_create_device(). La función zpci_create_device() devuelve un puntero de error que debe comprobarse antes de desreferenciarlo como puntero struct zpci_dev. Se añade la comprobación faltante en __clp_add(), donde se omitió al añadir la lista de escaneo en el commit corregida. Simplemente no añadir el dispositivo a la lista de escaneo provoca el comportamiento anterior.
