CVE-2026-64456

CVE-2026-64456 affects the Linux kernel virtio-rng driver. A malicious or buggy virtio-rng backend can over-report used.len to trap memcpy past the inline data buffer, reading adjacent slab memory. This enables a potential cross-boundary data leak of guest-kernel heap contents via /dev/hwrng and ...
