high Tenable Self-Hosted Container Security Plugin ID 469120

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: arm64: nv: Fix SPSR_EL2 restore
in kvm_hyp_handle_mops() kvm_hyp_handle_mops() resets the single-step state machine as part of rewinding
state for a MOPS exception by modifying vcpu_cpsr() and writing the result directly into hardware. In the
case of nested virtualization, vcpu_cpsr() is a synthetic value such that the rest of KVM can deal with
vEL2 cleanly. That means the value requires translation before being written into hardware, which is
unfortunately missing from the MOPS handler. Fix it by directly modifying SPSR_EL2 and avoiding the
synthetic state altogether, which will be resynchronized on the next 'full' exit back to KVM.
(CVE-2026-64555)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.299.116 or later.
