Description

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

iommu/tegra241-cmdqv: Fix alignment failure at max_n_shift

When configuring a kernel with PAGE_SIZE=4KB, depending on its setting of CONFIG_CMA_ALIGNMENT, VCMDQ_LOG2SIZE_MAX=19 could fail the alignment test and trigger a WARN_ON: WARNING: at drivers/iommu/arm/arm-smmu-v3/arm-smmu-v3.c:3646 Call trace: arm_smmu_init_one_queue+0x15c/0x210 tegra241_cmdqv_init_structures+0x114/0x338 arm_smmu_device_probe+0xb48/0x1d90

Fix it by capping max_n_shift to CMDQ_MAX_SZ_SHIFT as SMMUv3 CMDQ does.
