  3. CVE-2022-49435
In the Linux kernel, the following vulnerability has been resolved: mfd: davinci_voicecodec: Fix possible null-ptr-deref davinci_vc_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: mfd: davinci_voicecodec: Se corrige la posible eliminación de PTR nula con davinci_vc_probe(). Esto provocará una eliminación de PTR nula al usar 'res', si platform_get_resource() devuelve NULL, por lo que se debe mover el uso de 'res' después de devm_ioremap_resource() que lo comprobará para evitar la eliminación de PTR nula. Y se usa devm_platform_get_and_ioremap_resource() para simplificar el código.
