medium Tenable Cloud Security Plugin ID 469330

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: vgic: Free private_irqs
when init fails after allocation Companion to commit 250f25367b58 ("KVM: arm64: Tear down vGIC on failed
vCPU creation"), which added the missing kvm_vgic_vcpu_destroy() call to the kvm_share_hyp() failure path
in kvm_arch_vcpu_create(). The kvm_vgic_vcpu_init() failure path immediately above it has the same shape
and still needs the same cleanup. Call kvm_vgic_vcpu_destroy() when kvm_vgic_vcpu_init() fails so private
IRQs allocated before a redistributor iodev registration failure are released before the failed vCPU is
freed. (CVE-2026-64105)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.299.3 or later.
