Vulnerability from github – Published: 2025-03-17 18:31 – Updated: 2025-03-17 18:31

Details

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.

Severity

5.5 (Medium)
