In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Fix potential out-of-bounds read in iommummioshow In iommummiowrite(), it validates the user-provided offset with the check:
iommu->dbg_mmio_offset > iommu->mmio_phys_end - 4. This assumes a 4-byte access. However, the corresponding show handler, iommummioshow(), uses readq() to perform an 8-byte (64-bit) read. If a user provides an offset equal tommio_phys_end - 4, the check passes, and will lead to a 4-byte out-of-bounds read. Fix this by adjusting the boundary check to use sizeof(u64), which corresponds to the size of the readq() operation. - References
