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-2026-46014
A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM and Secure Virtual Machine SVM components. This vulnerability is due to missing save and restore handling for Last Branch Record LBR Model Specific Registers MSRs and MSRIA32DEBUGCTLMSR. A local attacker with access to a...

CVE-2026-46014
The CVE-2026-46014 issue affects the Linux kernel's KVM SVM path, where LBR MSRs (including MSR_IA32_DEBUGCTLMSR) were not properly saved/restored or enumerated by KVM_GET_MSR_INDEX_LIST, making save/restore of LBR state broken. The root cause is missing entries in msrs_to_save_base and restricti...
