medium Tenable Self-Hosted Container Security Plugin ID 475057

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/sva: Set handle->dev before the
 SVA handle is visible iommu_attach_device_pasid() installs the new SVA attach handle in the group PASID
 lookup before iommu_sva_bind_device() returns. A concurrent bind can therefore find and reuse the same
 handle after iommu_sva_lock is dropped. handle->dev was initialized after dropping iommu_sva_lock. This
 leaves a window where a racing bind can return a handle whose dev pointer is still NULL. A subsequent
 iommu_sva_unbind_device() can then dereference it via handle->dev->iommu_group. Initialize handle->dev
 before releasing iommu_sva_lock so any visible SVA handle is fully initialized. (CVE-2026-89451)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.700.7 or later.
