Descriptions
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.
