SUSE CVE-2026-46014

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-2026-46059

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine nSVM module. This vulnerability occurs when running nested virtual machines L2 guests with NRIPS Next Instruction Pointer Suppression disabled. After an L2 guest's initial run, the NextRIP value in vmcb02 may not be correctly...

CVE-2026-46071

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Avoid clearing VMCBLBR in vmcb12 svmcopylbrs always marks VMCBLBR dirty in the destination VMCB. However, nestedsvmvmexit uses it to copy LBRs to vmcb12, and clearing clean bits in vmcb12 is not architecturally defined...

CVE-2026-46059

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Always use NextRIP as vmcb02's NextRIP after first L2 VMRUN For guests with NRIPS disabled, L1 does not provide NextRIP when running an L2 with an injected soft interrupt, instead it advances the current RIP before...

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...

CVE-2026-46071 KVM: nSVM: Avoid clearing VMCB_LBR in vmcb12

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Avoid clearing VMCBLBR in vmcb12 svmcopylbrs always marks VMCBLBR dirty in the destination VMCB. However, nestedsvmvmexit uses it to copy LBRs to vmcb12, and clearing clean bits in vmcb12 is not architecturally defined...

EUVD-2026-32453

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Avoid clearing VMCBLBR in vmcb12 svmcopylbrs always marks VMCBLBR dirty in the destination VMCB. However, nestedsvmvmexit uses it to copy LBRs to vmcb12, and clearing clean bits in vmcb12 is not architecturally defined...

CVE-2026-46071

The CVE concerns the Linux kernel KVM nSVM path where svm_copy_lbrs() always marks VMCB_LBR dirty in the destination VMCB, while nested_svm_vmexit() copies LBRs to vmcb12 and clearing clean bits in vmcb12 is not architecturally defined. The fix moves vmcb_mark_dirty() to the call sites and drops ...

CVE-2026-45987 KVM: nSVM: Sync interrupt shadow to cached vmcb12 after VMRUN of L2

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...

CVE-2026-45987

CVE-2026-45987 affects the Linux kernel KVM/nSVM handling of nested VMs. After a VMRUN, nested_sync_control_from_vmcb02() syncs fields from vmcb02 to the cached vmcb12, which is supposed to be the authoritative copy for some controls. Specifically, int_state bit 0 (SVM_INTERRUPT_SHADOW_MASK) is w...

This is because the cached vmcb12 is use...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the svmcopylbrs function in KVM nSVM, where the VMCBLBR bit is cleared in vmcb12, potentially leading t...

PT-2026-43938

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the KVM nSVM component where the svm copy lbrs function always marks VMCB LBR as dirty in the destination VMCB. Because nested svm vmexit uses this to copy Last Branch...

CVE-2026-43133

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM nSVM module. When a nested virtual machine L2 guest executes VMSAVE/VMLOAD instructions, and these are not intercepted by the first-level hypervisor L1, KVM incorrectly uses vmcb02 instead of vmcb01 for managing guest state...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the fact that the VMLOAD/VMSAVE emulation in KVM nSVM does not always utilize vmcb01, potentially...

Unity Linux 20.1070e Security Update: kernel (UTSA-2026-001476)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001476 advisory. A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB virtual machine control block provided by t...
