CVE-2026-64513

CVE-2026-64513 affects the Linux kernel KVM x86 path, where CR8 intercept is recomputed on PPR update. Root cause: after a patch to speed up TPR below-threshold vmexits, apic_update_ppr() can omit a deliverable interrupt, causing kvm_lapic_update_cr8_intercept() and vmx_update_cr8_intercept() to ...

CVE-2026-64513 KVM: x86: Unconditionally recompute CR8 intercept on PPR update

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Unconditionally recompute CR8 intercept on PPR update The TPRTHRESHOLD field in the VMCS is used by VMX to induce VM exits when the guest's virtual TPR falls under the specified threshold, allowing KVM to inject...
