Description OSIDB Bzimport 2025-10-28 12:03:59 UTC 
In the Linux kernel, the following vulnerability has been resolved:

bus: fsl-mc: Check return value of platform_get_resource()

platform_get_resource() returns NULL in case of failure, so check its
return value and propagate the error in order to prevent NULL pointer
dereference.
