A vulnerability in the Linux kernel's KVM SEV implementation allows a malicious SEV-SNP guest to perform out-of-bounds reads and writes on the host kernel heap. This occurs due to improper validation of guest-controlled buffer sizes and entry indices when handling GHCB v2+ scratch areas, leading to heap corruption and information disclosure. The flaw enables leaking host heap layout information and potentially triggering use-after-free conditions. The vulnerability has been resolved in the Linux kernel.
