Executive Summary

This vulnerability is a race condition in the arm_lpae_split_blk_unmap function of io-pgtable-arm-common.c. It can cause memory corruption due to improper handling of TLB invalidation sequences and reference counts in protected virtualization domains. The issue arises when the function operates on translating domains instead of being restricted to idmap domains.

Impact Analysis

This vulnerability could allow a local attacker to escalate their privileges on the system. No additional execution privileges or user interaction are required for exploitation. It primarily affects systems using ARM-based IOMMU input-output page table management.

Mitigation Strategies

Apply the patch from the Android kernel commit 82cd807f41d89d5cf2b4c3ac7affdb91188baea7 to restrict arm_lpae_split_blk_unmap() to idmap domains only.
