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: iommufd: Fix wrong hwpt passed to
 iommufd_auto_response_faults on replace iommufd_hwpt_replace_device() calls:
 iommufd_auto_response_faults(hwpt, old_handle); passing the *new* hwpt together with the handle of the
 device's *old* domain. This should be a parameter mismatch: 1. Semantically,
 iommufd_auto_response_faults(x, handle) scans x->fault's deliver list and response xarray for groups
 matching "handle". A group is queued under the hwpt that was attached at fault-delivery time. old_handle
 is fetched *before* the domain switch, so its group lives on old->fault, not on the new hwpt->fault. 2.
 Historically, the first argument was "old". The routine was introduced by commit b7d8833677ba ("iommufd:
 Fault-capable hwpt attach/detach/replace") as __fault_domain_replace_dev() in fault.c, correctly calling
 iommufd_auto_response_faults(old, curr). Commit fb21b1568ada ("iommufd: Make attach_handle generic than
 fault specific") moved this into iommufd_hwpt_replace_device() in device.c and swapped it to "hwpt". This
 should be a refactor regression, not an intentional change. Fix this by passing "old" instead.
 (CVE-2026-80894)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.448.8 or later.
