CVE-2022-49323 (opens in a new tab)Amendment
The Red Hat security team deemed this advisory irrelevant for RHEL:8.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-cross-headers package and not the kernel-cross-headers package as distributed by RHEL.
In the Linux kernel, the following vulnerability has been resolved:
iommu/arm-smmu: fix possible null-ptr-deref in arm_smmu_device_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. And use devm_platform_get_and_ioremap_resource() to simplify code.
