CVE-2025-40300

The CVE-2025-40300 issue affects the Linux kernel’s x86/vmscape mitigation. The vulnerability arises from insufficient branch predictor isolation between a guest and a userspace hypervisor, which is mitigated by conditionally issuing an IBPB after VMexit and before returning to userspace. The fix...
