In the Linux kernel, the following vulnerability has been resolved: hwrng: virtio: clamp device-reported used.len at copy_data() random_recv_done()… (CVE-2026-64456)CVE-2026-64456 0 A vulnerability in the Linux kernel's virtio-rng driver allowed a malicious or buggy virtio-rng backend to report an excessive used.len value, causing an out-of-bounds read past an internal buffer. This could lead to guest kernel memory disclosure via the /dev/hwrng interface. The issue affects the guest environment and can leak adjacent kernel slab memory into the guest's random number generator output. The vulnerability has been resolved by clamping the device-reported length and adding bounds checks. Join the discussion | GCVE Database | 07/25/2026, 12:31:36 UTC Added: 07/25/2026, 23:08:56 UTC |
