CVE-2022-49449
In the Linux kernel, the following vulnerability has been resolved: pinctrl: renesas: rzn1: Fix possible null-ptr-deref in sh_pfc_map_resources() It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res'…
Does this matter?
Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: pinctrl: renesas: rzn1: Fix possible null-ptr-deref in sh_pfc_map_resources() 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.
