CVE-2026-43483

CVE-2026-43483 (Linux kernel, KVM/VMX-SVM) fixes a flaw in SVM AVIC handling where CR8 write interception could remain enabled after AVIC activation. The patch explicitly sets/clears CR8 interception when AVIC is (de)activated to prevent the dangling intercept, which could cause TPR desynchroniza...
