CVE-2026-46131

Summary
In the Linux kernel, the following vulnerability has been resolved:
KVM: x86: check for nEPT/nNPT in slow flush hypercalls
Checking is_guest_mode(vcpu) is incorrect, because translate_nested_gpa() is only valid if an L2 guest is running with nested EPT/NPT enabled. Instead use the same condition as translate_nested_gpa() itself.
