CVE-2026-89930 is a critical vulnerability in the Linux kernel's KVM nested virtualization (nVMX) implementation. It involves improper handling of local TLB flushes when a nested VM-Enter operation fails. Specifically, KVM may fail to perform necessary local TLB flushes after a failed nested VM-Enter, potentially leading to stale TLB entries and inconsistent processor state. This flaw could impact confidentiality, integrity, and availability of the system.
