high Tenable Self-Hosted Container Security Plugin ID 469532

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: Bound used_lrs when
 flushing the pKVM hyp vCPU flush_hyp_vcpu() copies the host vGIC state into the hyp's private vCPU on
 every run. The vGIC list register save and restore use used_lrs as their loop bound and expect it to stay
 within the number of implemented list registers. While this is generally the case, flush_hyp_vcpu() copies
 vgic_v3 verbatim and does not enforce this, so a value provided by the host is used at EL2 to index
 vgic_lr[] and access ICH_LR<n>_EL2 (host -> EL2). Fix by clamping used_lrs to the number of implemented
 list registers after the copy, as the trusted path already does in vgic_flush_lr_state(). The number of
 implemented list registers is constant after init, so it is replicated once from
 kvm_vgic_global_state.nr_lr into hyp_gicv3_nr_lr rather than read on every entry. (CVE-2026-64287)

Solution

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