Summary
CVE-2022-49323 is a vulnerability affecting the Linux kernel that has been addressed. In the ionmu/arm-smmu driver, a null-pointer dereference occurred when using 'res' in the function 'arm_smmu_device_probe()' if 'platform_get_resource()' returned NULL. To prevent this issue, the order of operations has been changed, with 'devm_ioremap_resource()' being called before using 'res'. Additionally, 'devm_platform_get_and_ioremap_resource()' has been introduced to simplify the code.
