EUVD-2026-80530

In the Linux kernel, the following vulnerability has been resolved: KVM: nVMX: Service local TLB flushes on failed nested VM-Enter KVM services local TLB flushes on "full" nested VM-Exits through nestedvmxvmexit, but not if a nested VM-Enter fails e.g. due to failed VMCS checks in...

CVE-2026-89930

CVE-2026-89930 affects the Linux kernel's KVM nVMX subsystem (nested virtualization). The root cause is that KVM failed to service local TLB flushes when a nested VM-Enter failed (e.g., due to failed VMCS checks in nested_vmx_enter_non_root_mode()). Specifically, a failed VM-Enter would update la...

CVE-2026-89929

CVE-2026-89929 affects the Linux kernel KVM subsystem, specifically the nested virtualization (nVM ) code path that emulates the INVVPID instruction. When a guest L1 vCPU migrates between physical CPUs and issues INVVPID, KVM executes the instruction on the current physical CPU rather than the on...

CVE-2026-89929 KVM: nVM: Ensure INVVPID is emulated on the correct physical CPU

In the Linux kernel, the following vulnerability has been resolved: KVM: nVM: Ensure INVVPID is emulated on the correct physical CPU When emulating INVVPID, KVM executes INVVPID on the physical CPU using vpid02 instead of the L1 assigned VPID, after doing some validations on the operands. However...

CVE-2026-89811

CVE-2026-89811 affects the Linux kernel in the drm/amdkfd subsystem (AMD KFD driver). The MES (Micro Engine Scheduler) fails to perform a heavy-weight TLB invalidation after unmapping GPU queues—unlike HWS, which does so automatically. This creates a race condition where in-flight DMA descriptors...
