CVE-2026-64456

A flaw was found in the Linux kernel's virtio-rng driver. A malicious or buggy virtualized hardware random number generator virtio-rng backend can report an overly large data length to the guest operating system. This unchecked length can lead to an out-of-bounds read, causing the driver to acces...

CVE-2026-66034

A missing bounds check in the libssh2 publickey subsystem allows malicious SSH servers to trigger a client-side out-of-bounds read, leaking heap pointers that could enable security bypasses, denial of service, or code execution. Mitigation To mitigate this, strictly avoid connecting to untrusted...
