Summary
CVE-2026-53053 affecting package kernel 6.6.150.1-1
Details

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

iommu/amd: Fix clone_alias() to use the original device's devid

Currently clonealias() assumes first argument (pdev) is always the original device pointer. This function is called by pciforeachdma_alias() which based on topology decides to send original or alias device details in first argument.

This meant that the source devid used to look up and copy the DTE may be incorrect, leading to wrong or stale DTE entries being propagated to alias device.

Fix this by passing the original pdev as the opaque data argument to both the direct clonealias() call and pciforeachdmaalias(). Inside clonealias(), retrieve the original device from data and compute devid from it.
