high Tenable Self-Hosted Container Security Plugin ID 475593

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: x86/amd_node: Fix PCI device reference
counting in amd_smn_init() The local "root" pointer is a temporary variable used during the device search.
Therefore, refcount related to the search iterators should be cleaned up after the search is complete. Use
the __free() cleanup macro to ensure the refcount is decremented when the temporary pointer goes out of
scope. Additionally, increment the refcount when caching a root pointer. This ensures the in-use refcount
is separate from the temporary search refcounting. Finally, drop the redundant "root = NULL" before the
second search loop. The pci_get_class() iterator always decrements the refcount of its "from" argument, so
the first loop can only fall through with "root" already NULL. (CVE-2026-97946)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 20198.0.0 or later.
