CVE-2025-38351
CVE-2025-38351 affects the Linux kernel KVM component (x86) when Hyper-V hypercalls are enabled. The issue arises in PV TLB flush processing where non-canonical GVAs can reach INVVPID/INVLPGA paths, potentially triggering VM-Fail on Intel hardware (AMD may ignore). In practice, this can allow a g...
