CVE-2022-49323: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: before 5.10.122 (fixed in 5.10.122); from 5.11, before 5.15.47 (fixed in 5.15.47); from 5.16, before 5.17.15 (fixed in 5.17.15); from 5.18, before 5.18.4 (fixed in 5.18.4)
