Description OSIDB Bzimport 2025-02-26 03:19:58 UTC 
In the Linux kernel, the following vulnerability has been resolved:

mtd: rawnand: intel: fix possible null-ptr-deref in ebu_nand_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.
