Echo: linux: security update to 6.12.94-1

high Tenable Cloud Security Plugin ID 459470

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Fix clone_alias() to use
 the original device's devid Currently clone_alias() assumes first argument (pdev) is always the original
 device pointer. This function is called by pci_for_each_dma_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 clone_alias() call
 and pci_for_each_dma_alias(). Inside clone_alias(), retrieve the original device from data and compute
 devid from it. (CVE-2026-53053)

Solution

Update the linux library and its related packages to version 6.12.94-1 or later.
