CVE-2025-38351

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/hyper-v: Skip non-canonical addresses during PV TLB flush In KVM guests with Hyper-V hypercalls enabled, the hypercalls HVCALLFLUSHVIRTUALADDRESSLIST and HVCALLFLUSHVIRTUALADDRESSLISTEX allow a guest to request...

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...
