Technical description

In the Linux kernel, the following vulnerability has been resolved:

spi: wpcm-fiu: Fix potential NULL pointer dereference in wpcm_fiu_probe()

platform_get_resource_byname() can return NULL, which would cause a crash

when passed the pointer to resource_size().

Move the fiu->memory_size assignment after the error check for

devm_ioremap_resource() to prevent the potential NULL pointer dereference.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
