CVE-2025-40038

CVE-2025-40038 affects the Linux kernel KVM/VMX SVM fastpath emulation for VM-Exit handling. The issue arises when the next RIP is not valid (e.g., nrips=false); KVM must decode and emulate the instruction to skip it, which requires reading guest memory. Reading guest memory through the emulator ...
