CVE-2026-64286

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Clear hyprunningvcpu when flushing the pKVM hyp vCPU flushhypvcpu copies the host vCPU context into the hyp's private vCPU on every run. ctxttovcpu expects a guest context to have a NULL hyprunningvcpu, which is only...

CVE-2026-64287 KVM: arm64: Bound used_lrs when flushing the pKVM hyp vCPU

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Bound usedlrs when flushing the pKVM hyp vCPU flushhypvcpu copies the host vGIC state into the hyp's private vCPU on every run. The vGIC list register save and restore use usedlrs as their loop bound and expect it to...

CVE-2026-64287

CVE-2026-64287 affects the Linux kernel’s KVM on arm64. The issue stems from flush_hyp_vcpu() copying host vgic_v3 state to the hyp’s vCPU and not enforcing the expected bound on list registers, which can lead to out-of-bounds access to ICH_LR_EL2 when host values exceed the number of implemented...

PT-2026-64507

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the KVM arm64 implementation where the flush hyp vcpu function copies the host vCPU context into the hyp's private vCPU during every run. Because the ctxt to vcpu...

CVE-2026-46147

CVE-2026-46147 concerns the Linux kernel KVM on ARM64, where two bugs in vCPU initialisation can leak pin references to host vCPU/SVE pages and allow observation of a partially initialised vCPU object. The fixes extract a helper for vCPU registration, ensure proper unpinning on error, and enforce...

EUVD-2026-32774

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Fix pin leak and publication ordering in pkvminitvcpu Two bugs exist in the vCPU initialisation path: 1. If a check fails after hyppinsharedmem succeeds, the cleanup path jumps to 'unlock' without calling unpinhostvcp...

CVE-2025-48623

In initpkvmhypvcpu of pkvm.c, there is a possible out of bounds write due to improper input validation. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation...
