CVE-2026-46071 (opens in a new tab)Amendment
The Centos security team deemed this advisory irrelevant for Centos:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-devel package and not the kernel-devel package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
KVM: nSVM: Avoid clearing VMCB_LBR in vmcb12
svm_copy_lbrs() always marks VMCB_LBR dirty in the destination VMCB. However, nested_svm_vmexit() uses it to copy LBRs to vmcb12, and clearing clean bits in vmcb12 is not architecturally defined.
Move vmcb_mark_dirty() to callers and drop it for vmcb12.
This also facilitates incoming refactoring that does not pass the entire VMCB to svm_copy_lbrs().
