SUSE CVE-2026-46131

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

CVE-2026-46131

A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine x86 virtualization module. An incorrect check for nested EPT/NPT Nested Extended Page Tables/Nested Nested Page Tables in slow flush hypercalls could lead to improper handling of L2 guests. This vulnerability arises because t...

CVE-2026-46131

CVE-2026-46131 affects the Linux kernel KVM x86 code. The issue is a faulty check in slow flush hypercalls where is_guest_mode(vcpu) was used incorrectly; translate_nested_gpa() is only valid when an L2 guest runs with nested EPT/NPT enabled, so the condition should match translate_nested_gpa() i...
