- Summary
- pinctrl: renesas: rzn1: Fix possible null-ptr-deref in sh_pfc_map_resources()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
pinctrl: renesas: rzn1: Fix possible null-ptr-deref in shpfcmap_resources()
It will cause null-ptr-deref when using 'res', if platformgetresource() returns NULL, so move using 'res' after devmioremapresource() that will check it to avoid null-ptr-deref. And use devmplatformgetandioremap_resource() to simplify code.
