high Tenable Cloud Security Plugin ID 472633

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: KVM: nVMX: Ensure
KVM_REQ_GET_NESTED_STATE_PAGES is cleared on VM-Exit Always check and clear KVM_REQ_GET_NESTED_STATE_PAGES
when emulating a nested VM-Exit to ensure the request is cleared, even when KVM was built with
CONFIG_KVM_HYPERV=n, as KVM subtly relies on the "check" to clear the flag and thus avoid double-mapping
the vmcs12 pages, e.g. if KVM manages to bail from VM-Enter without processing the request, and then
emulates VMLAUNCH or VMRESUME. (CVE-2026-89931)

Solution

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