EUVD-2026-32395

In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Add missing save/restore handling of LBR MSRs MSRIA32DEBUGCTLMSR and LBR MSRs are currently not enumerated by KVMGETMSRINDEXLIST, and LBR MSRs cannot be set with KVMSETMSRS. So save/restore is completely broken. Fix it ...

CVE-2026-46014

CVE-2026-46014 is a Linux kernel vulnerability affecting KVM/SVM where save/restore of LBR and DEBUGCTL MSRs was incomplete. The issue arose because MSR_IA32_DEBUGCTLMSR and LBR MSRs were not included in the msrs_to_save_base list and could not be set/restored properly, breaking save/restore acro...

CVE-2026-45987

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Sync interrupt shadow to cached vmcb12 after VMRUN of L2 After VMRUN in guest mode, nestedsynccontrolfromvmcb02 syncs fields written by the CPU from vmcb02 to the cached vmcb12. This is because the cached vmcb12 is use...
