  3. CVE-2022-49494
In the Linux kernel, the following vulnerability has been resolved: mtd: rawnand: cadence: fix possible null-ptr-deref in cadence_nand_dt_probe() It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref. And use devm_platform_get_and_ioremap_resource() to simplify code.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mtd: rawnand: cadence: se corrige un posible null-ptr-deref en cadence_nand_dt_probe(). Provocará un null-ptr-deref al usar 'res', si platform_get_resource() devuelve NULL, así que pase a usar 'res' después de devm_ioremap_resource() que lo comprobará para evitar un null-ptr-deref. Y use devm_platform_get_and_ioremap_resource() para simplificar el código.
