CVE-2021-1064

Information disclosure or service interruption via pointer dereference

Published Jan 8, 2021 · Updated Aug 3, 2024

Pointer dereference in NVIDIA Virtual GPU Manager 8.0 through 8.5 and 11.0 through 11.2 allows local users to disclose information or interrupt service. The vGPU plugin converts an untrusted value into a pointer and dereferences it without establishing that the resulting address is valid. Low-privileged local access is required; NVIDIA does not specify whether denial of service stops the plugin, a guest, or the host.
